Kingdom of Ash is the explosive finale of Sarah J. Maas’s Throne of Glass saga. With Terrasen on the brink of annihilation, Aelin Galathynius—fire-blooded queen and last hope of a shattered continent—endures captivity under Maeve, a cruel immortal queen, while her allies scramble to hold the line against Erawan’s Valg legions. Across seas and deserts and snowbound mountains, fractured courts and long-enemy peoples are forced into uneasy unity.
As the war escalates into sieges, witch towers, and apocalyptic magic, the story narrows into one brutal question: what will it cost to close the Wyrdgate and stop the Valg forever? The answer demands impossible choices, devastating sacrifice, and hard-won hope. It’s a finale that balances sweeping battles with intimate loyalty—proving again that, when the world is ending, it’s the people you love who determine who you become.
