Luna Veil enters Blackthorn Academy as the only human in a world ruled by beast clans. After her blood mysteriously calms four powerful heirs—a dragon, wolf, panther and snake—she is forced into a dangerous resonance test with them. Attraction grows, but so do the secrets surrounding her father and the Academy. When Luna discovers she is part of an illegal experiment that began before her birth, she refuses to become anyone’s chosen mate or test subject. To survive, she must awaken her power, expose the truth and choose her own future.
