In a follow-up to Carla Swafford's sexy Circle of Desire, the agents of The Circle—a top-secret group of assassins—are back and on the hunt for a dangerous drug lord capable of bringing women to the brink of pleasure . . . and devastation.

Marie Beltane, a lowly data entry specialist for The Circle, resents being treated like a little girl and wants to help by proving she's worthy of being a full-fledged operative. Disobeying Arthur Ryker's orders to stay out of the way, she accepts a simple fact-finding assignment—only to have everything go horribly wrong. Now she's been injected with the drug responsible for the deaths of four local women, a drug that puts her sex drive into overdrive.

Ryker wants nothing more than to keep Marie safe from the world. He's already killed to protect her from one madman, and he may have to do it again. While on a search for an antidote to her mysterious drug, he falls into a trap and must fight a new evil. Now he must become the monster he's always feared to save the woman he's always loved.
