In a world of shattered continents floating in endless sky, the once legendary elvish thief Anuhea hides atop a mountain drinking away his memories. The guilt of allowing his only apprentice, Tinnu, to die when the world broke has made him resigned to waste away the rest of his long life... until Astra, a once powerful shapeshifter trapped in the body of a nightingale, arrives to enlist his help. One of two surviving members of the resistance against the new god who undid the world, she needs Anuhea to rescue the other: Tinnu's brother, Ivellios, who has been captured. Driven by his debt to the dead, Anuhea sets off to make the greatest theft of his career.
