When her sister goes missing, Ana has only one priority: find Tasha. She can't give the police all the facts because they wouldn’t believe that magic is involved, and she doesn't have time for the inconvenient rush of desire she feels for Gideon, the security expert she hires to rescue her sister.To save a kidnapped woman, Gideon must work closely with the victim's bewitching sister Ana—without revealing his true identity as a Guardian or letting their powerful attraction distract him. But as the investigation and their feelings deepen, he faces a terrible choice: obey his Celestial orders, or protect Ana from the same evil that stole her sister.
