Aidan Montgomery refuses to give up on Amelia. Once she's rescued from the Keeper's hold, he intends to prove his love is more than a side effect of the prophecy, even if doing so leads him away from his pack on a journey that will irrevocably change them both.
When the past and present collide, and the shocking origin of the Immortals is revealed, Amelia and Aidan are forced back to Cresthaven to end a war that never should have started.
