The author of Iron Cast delivers "a thrilling adventure story" in this YA fantasy novel of dangerous rebellion against rules with the power of prophecy (Kirkus). In the city of Eldra, people are ruled by ancient prophecies. For centuries, the high council has stayed in power by virtue of the prophecies of the elder seers. After the last infallible prophecy came to pass, growing unrest led to murders and an eventual rebellion that raged for more than a decade. Now Cassa, the orphaned daughter of rebels, is determined to fight back against the high council, which governs Eldra from behind the walls of the citadel. Her only allies are no-nonsense Alys, easygoing Evander, and perpetually underestimated Newt. As Cassa struggles to live up to her parents' legacy, she and her friends try to uncover the mystery of the final infallible prophecy—before it's too late to save the city.
