In a world struggling back from the brink of apocalypse, life is harsh. And for Elspeth Gordie, it is also dangerous.

And her worries only multiply when she is exiled to the mountain compound known as Obernewtyn, where—for all her talents—Elspeth may finally and truly be out of her depth. Then she learns she's not the only one concealing secrets at Obernewtyn.
