Eighteen-year-old Lily Isaac is a half-blood. Her father a vampire and her mother a human, Lily is seen as a lesser being from the rest of society. She doesn’t let this keep her from obtaining her one true goal in life: to become a valiant Vanguard—a vampire knight for the Palace of the Bloodprince. But earning a position as a Vanguard inside Silvercity means passing one final test: a hunt in which she must return with the claws of a dead werewolf.

When Lily finds herself overpowered by a wolf, barely escaping with her life, her chances as a Vanguard slip through her fingers. But she is recognized by the Bloodpince for another reason: her blood is as valuable to him as gold. She finds herself working in the Palace, where the prince’s shaky health seems to regenerate the longer he feeds from her.

As the days pass, and their feedings become more intimate, Lily finds herself drawing closer to the prince. But as a stranger begins to appear from the shadows, the prince’s life is threatened. The only way Lily can protect him is by agreeing to spy on the palace for a pack of werewolves who want to destroy Silverycity and the prince’s legacy.

In time, Lily finds her heart torn between two souls. One a beautiful and noble prince with a cruel past, the other a daring, dangerous alpha who wishes only to destroy him.

Unfortunately for Lily, choosing one could mean sacrificing the other.
