Cassandra Christo is on a quest for answers in the mysterious deaths of her mother and stepbrother. But when she returns to her childhood home on the Pacific Coast of Baja, Mexico, Cassie runs into two major obstacles: her corrupt stepfather, and Rio Santana, Saul's right-hand man and the person she unknowingly let into her heart after he comforted her during the darkest moment of her life.

Rio's been fantasizing about reconnecting with Cassie for months. But not here and sure as hell not now. As an undercover agent with U.S. Immigration and Customs Enforcement, he's only weeks away from finalizing transport of a terrorist cell over the U.S.-Mexico border, and he definitely doesn't have time for this wild attraction to Cassie, let alone the risk it poses to his cover.

When Cassie's stepfather grows nervous about her investigation and orders Rio to use seduction as a last-ditch effort to keep her from learning too much, the heat between them turns into a full blown inferno. And as the end of the operation draws closer, Rio knows if he tells Cassie the truth about who and what he is, it won't only jeopardize his mission, it may result in him losing her forever. And if he doesn't, his lies and deception could get them both killed.
