Dr. Kayleigh Lauderdale possesses the only cure for what's killing the city's witches. Desperate to acquire it, the resistance sends their best agent, but Shawn Lowehas his own agenda and it doesn't include saving anyone—least of all, the daughter of his sworn enemy. He has to ignore the blistering attraction he feels the instant they meet, because he can't give in until he gets what he wants. He just never counted on wanting her . . .

Kayleigh can't believe how out of control Shawn makes her feel. He lies to her with one breath and excites her beyond reason with the next. A reckless encounter could steal her heart, while the danger hovering over the city may prove too much for either of them to handle. When the world turns upside down, it will take everything Kayleigh and Shawn have to hold on . . . to life, to hope, to each other.
