When the Sleepers wake. Once, that phrase meant never. The Sleepers were a myth, part of a story told to children. But in truth, the Sleepers, ancient princes in the court of the Winter Queen, were imprisoned in slumber by the gods themselves⁠—in the cold, dark ruins of the ancient city that lies buried beneath the capitol of the Empire. And that prison is fraying, at last. Jewel ATerafin has faced the Oracle's test. She has control of the prophetic powers that she once considered a curse and a burden. She will find her way to the Winter Queen, and she will ask⁠—or beg⁠—the Winter Queen to intervene to save her kind, her House, and everything she loves. But she is mortal, and time has never been her friend. The demons are waiting to bar her way, bringing battle to the hidden ancient paths on which she must travel. To win, she must face the true meaning of the Oracle's test, and risk sanity and life to make the choice that has always lurked at the heart of the Firstborn's test. And even then, it might be too late.
