Part 1: Heir of Ash

Heir of Fire Chapter 1

Celaena Sardothien has spent two weeks in Varese, Wendlyn’s capital. The King of Adarlan sent her to assassinate Wendlyn’s king and crown prince and to steal the kingdom’s naval defense plans, but one look at the heavily guarded castle was enough to put her off the mission.

Celaena had her own agenda. She wanted to track down Queen Maeve of the Fae and learn how to destroy the Wyrdkeys, three powerful artifacts the King of Adarlan was using to build his empire. She had vowed to Nehemia, her recently deceased friend, that she’d see it through.

That plan fell apart the day Celaena watched Crown Prince Galan Ashryver ride out through the castle gates. A blockade runner beloved by his people, Galan was actively fighting against Adarlan, and Celaena had a clear shot at him from a nearby rooftop. She followed him to the city walls but never took the shot.

After that, Celaena stopped caring altogether. She reasoned that even Galan, commanding a full armada, was barely making a dent against the King of Adarlan. She was only one person. What could she possibly do that would matter? Since then, she’s been lying on rooftops drinking wine and starting tavern brawls just to feel something.

Then a homeless woman mistakes Celaena for a fellow vagrant competing for street space. Before Celaena can process how far she has fallen, a man laughs from the shadows behind her.

Heir of Fire Chapter 2

Cornered in an alley, Celaena watches as a Fae warrior steps out of the shadows and moves toward her. She immediately recognizes that Maeve sent the warrior. Instead of running, Celaena sees an opportunity, since she has already been trying to find a way to reach Maeve herself. 

Celaena walks up to the warrior and greets him warmly, loud enough for the bystanders around them to hear. She buys herself cover so no one realizes who she really is. The warrior isn’t interested in playing along and simply tells Celaena to come with him. She follows the warrior through the city to a square where two horses wait.

Before they set off, Celaena manages to learn one thing from the Fae warrior. His name is Rowan. He tells her that he’s taking her where she’s been summoned, and that’s enough for her. Celaena gets on her horse, and together they ride out of the city toward Doranelle.

Heir of Fire Chapter 3

Chaol has endured the same nightmare for a month. In it, Celaena kills Dorian the way she killed Archer, and Chaol can’t stop her. He’s still shaking it off at dinner when Dorian notices and asks what’s wrong. Chaol deflects by mentioning his father’s upcoming return to Anielle and the expectation that he go along.

Then Aedion Ashryver enters the Great Hall and silences the room. Chaol is struck by how strongly Aedion resembles Celaena, with the same eyes, coloring, and unmistakable bloodline. Aedion approaches the King of Adarlan with barely veiled contempt and hands over spoils from a rebel camp. The king orders him to appear at a council meeting the next day.

As Aedion passes through the room, he gets close enough for Chaol to spot a black ring on his finger, the same kind worn by those under the king’s influence.

Aedion drops into the seat across from Chaol and Dorian and needles both men, bringing up the death of a witch Matron and asking about the King’s Champion. Dorian’s temper slips, and the air shifts as his magic begins to leak out. Chaol pulls himself and Dorian away before it escalates further.

Walking back to his tower, Dorian admits his magic worsens when he’s scared or angry. Chaol tells Dorian that protecting him has always been his first priority. Dorian then asks why Chaol actually sent Celaena to Wendlyn. Chaol gives no answer and walks away.

Heir of Fire Chapter 4

Manon Blackbeak, an Ironteeth witch posing as a Crochan, has been waiting for this night. When three men break into her cottage, meaning to kill her, she slips out of the closet where she’s been hiding and gets behind the first man without the man noticing. She reveals her iron teeth and claws and kills him. She takes out the second man in the main room just as quickly. The third man stumbles upon the aftermath and runs. Manon lets the man get a head start into the tall grass field outside, then goes in after him.

Heir of Fire Chapter 5

Celaena and Rowan ride south through Wendlyn toward the Cambrian Mountains, which separate the mortal lands from Queen Maeve’s immortal realm. When night falls, Rowan stops to make camp in a dense forest. He waters the horses and hands Celaena food without a word, and they eat in near-total silence. When Celaena finally asks why they cannot light a fire, Rowan says only that the dangers in the forest aren’t mortals.

Shortly after, Celaena spots small faeries watching her from the shadows. She grabs her dagger but doesn’t act, and Rowan stays still, seemingly unbothered. More faeries gather, drawn to her Fae bloodline. Celaena thinks about how the Little Folk have always recognized what she is, then wonders whether they know about the wars that devastated Terrasen and wiped out so many of their kind. 

On impulse, Celaena whispers to the faeries that their kin in the West survived. The faeries vanish, and although Rowan never moves, he gives her the impression he’d been aware of the whole thing.

Heir of Fire Chapter 6

Dorian is summoned to breakfast, where his father orders him to spend the day with Aedion. Dorian objects, but the King of Adarlan won’t budge. The outing becomes a garden walk, and when the guards briefly fall behind, Aedion trips Dorian into a rosebush. They exchange almost nothing for the rest of the walk, and Aedion’s parting comment, made when he notices Dorian’s bleeding hand, sounds more like a warning.

At the healers’ catacombs, Dorian meets Sorscha, a young healer who has treated Dorian, Chaol, and Celaena many times without any of them noticing her. Sorscha tends his cuts and admits she doesn’t always record what she observes, hinting that she’s been keeping their secrets on her own. Dorian thanks her and leaves.

Dorian never even knew Sorscha’s name despite how often she cared for him, Chaol, and Celaena. Over months, Sorscha pieced together the relationships among them and concluded that Celaena is Celaena Sardothien, the world’s most feared assassin. None of them ever truly saw her, yet Sorscha has quietly been in love with Dorian for six years.

Heir of Fire Chapter 7

Celaena and Rowan spend several uncomfortable days riding through the Cambrian Mountains, camping in the cold each night with barely enough food to take the edge off Celaena’s hunger. She says almost nothing the entire time, unwilling to build any kind of rapport with Rowan.

Eventually, Celaena and Rowan leave the main road and reach an ancient fortress built into the mountainside. Guards stand watch, and magic wards announce their approach before they even get close. Rowan walks Celaena inside without a word, and she sizes up the place the way she always does in unfamiliar territory.

Rowan brings Celaena to a small office, and the woman waiting there stops Celaena cold. The woman is Maeve, Queen of the Fae, who also happens to be Celaena’s aunt. Maeve addresses her not as Celaena but by her true name, Aelin Galathynius, a name she has spent the last decade trying to leave behind.

Heir of Fire Chapter 8

Celaena comes face to face with Maeve, who wastes no time revealing that she knows Celaena is actually Aelin Galathynius. Maeve tells Celaena that her parents broke Fae law by eloping and that her mother repeatedly put off fulfilling a promise to bring Celaena before her.

Maeve then brings up the subject of the Wyrdkeys, letting Celaena know that her spies have been watching. She agrees to answer Celaena’s questions about them, but she sets her terms. Celaena must first prove herself worthy of entering Doranelle by training under Rowan at Mistward until he judges her ready. Celaena agrees, and Maeve ends the meeting by telling Celaena she wants her to become queen.

Walking back through the fortress, Celaena picks a fight with Rowan and says something cruel enough that Rowan punches her. She tries to hit back, but Rowan outmaneuvers her without much effort. He then takes all of Celaena’s weapons and tells her she’ll be on kitchen duty every morning alongside her training.

That night, Celaena lies awake in a sparse, cold room and stares out at the stars in the direction of Terrasen. She sits with the uncomfortable truth that she has spent ten years running instead of standing her ground.

Heir of Fire Chapter 9

Manon stands guard near the Acanthus River while her grandmother, the High Witch of the Blackbeak Clan, meets with a duke from a traveling caravan. Once the meeting ends, Manon and her grandmother walk north, and the Matron begins to share what was decided.

Mother Blackbeak instructs Manon to dispatch three members of the Thirteen in separate directions to gather every Blackbeak witch and direct the witches to the Ferian Gap. Any other Ironteeth witches the Thirteen encounter along the way should receive the same message.

The Matron delivers two pieces of news. Baba Yellowlegs has been found dead in Rifthold, and no one knows who killed her or why. More significantly, the King of Adarlan has made an offer to all the Ironteeth clans. He has spent years breeding wyverns in the Ferian Gap and wants the witches to serve as his aerial cavalry. When their service ends, the witches keep the wyverns and use them to reclaim their homeland in the Western Wastes.

For Manon, who’s been earthbound for ten years since magic vanished, the prospect of flying again feels immediate and electric. Manon and her grandmother turn their eyes toward the mountains.

Heir of Fire Chapter 10

After a long day, Chaol returns to his quarters and finds two of his guards missing from their posts outside the Great Hall. The guards who stayed behind admit that General Aedion Ashryver invited the missing men to join his party in Rifthold, telling them Chaol would be fine with it. Furious, Chaol punishes the guards who didn’t report the situation and heads into the city to deal with it himself.

Chaol tracks down the party to a tavern Aedion has taken over for the night. Chaol finds several of his own guards there, drinking and enjoying themselves, and sends them all back to the castle. Then Chaol goes looking for Aedion, but the general has already slipped out. A courtesan tells Chaol that Aedion left about an hour ago with another woman, destination unknown.

Before leaving, Chaol picks up another piece of bad news. Aedion’s military legion, the Bane, is on its way to Rifthold, and the soldiers apparently plan to make Aedion’s current parties look tame by comparison, with Chaol’s guards openly invited to join in. Chaol worries the chaos will put him under the king’s scrutiny at a time when he can least afford it. He decides to go to Aedion’s next party to find something he can hold over the general to make him fall in line.

Heir of Fire Chapter 11

Celaena wakes before dawn to find a healing salve, fresh clothes, soap, and water outside her door. Rowan left them at Maeve’s instruction. She cleans herself up and heads to the kitchen for scullery duty.

Rowan introduces Celaena to Emrys, an older half-Fae cook, and to Luca, a chatty young man. Celaena gives her name as Elentiya, and Rowan leaves her with them. The breakfast rush proves chaotic and relentless, but she finds unexpected comfort in being completely unknown to everyone around her.

Once things quiet down, Celaena sits and eats. Emrys and Luca are startled by how hungrily she goes at it. Over the meal, Luca and Emrys explain that most of the people living at Mistward are demi-Fae who weren’t considered gifted enough to be taken to Doranelle. Rowan has served Maeve for so long that even the oldest residents remember him from their childhoods. Luca suggests that staying at Mistward permanently might not be so bad, but Celaena shuts the idea down and insists she can handle whatever Rowan throws at her.

Celaena moves on to the dishes, and the thought she keeps circling back to is that she’s forgotten what freedom ever felt like.

Heir of Fire Chapter 12

The Blackbeak Clan arrives last at the Ferian Gap and gets the worst rooms in the Omega mountain. Since then, Manon has already broken up a brawl between her Second, Asterin, and a Yellowlegs sentinel. She punished Asterin with three blows for her part in the fight.

That evening, the witches hold a memorial for Baba Yellowlegs, the recently deceased Yellowlegs High Witch. Nobody knows what happened to Baba Yellowlegs, and the uncertainty unsettles Manon more than the death itself.

The next morning, the three Clan Matrons and their coven leaders assemble at the black bridge between the Omega and the Northern Fang. Manon sizes up the other two heirs. Petrah of the Bluebloods stays reserved and unreadable, while Iskra of the Yellowlegs shows open hostility.

The group crosses to the Northern Fang, where soldiers guide them through the wyvern breeding and training operation. At a viewing platform above a training pit, a soldier explains how the creatures are sorted and trained. When the Matrons ask when the witches can begin choosing their mounts, the soldier says they’ll start on calmer animals before working up to the bulls.

To demonstrate, the soldier calls a bull wyvern named Titus into the pit. While the soldiers show Titus off, he lunges and kills one of the men. Manon decides she wants Titus as her mount and nothing less.
