The Hematoi are the powerful descendants of gods and mortals. Children of two Hematoi are pure-bloods with godlike abilities, but half-bloods like seventeen-year-old Alexandria have only two options in life: train to become deadly Sentinels who hunt rogue daimons, or spend their lives as lowly servants. Alex would much rather risk her life fighting in the shadows than waste it scrubbing toilets. But surviving her intense training at the Covenant is not her only problem. The school has strict rules, and the most unbreakable one is that relationships between pure-bloods and half-bloods are strictly forbidden. Unfortunately, Alex is crushing hard on her totally hot, pure-blood trainer, Aiden. Falling for Aiden is dangerous, but staying alive is her biggest challenge. If Alex fails in her duty to graduate, she faces a fate worse than death or slavery: being turned into a daimon herself, and being hunted down by the very boy she loves.
