As the top assassin at The Circle, a shadowy group of mercenaries, Olivia St. Vincent can hunt down anyone. She's been trained since she was a teenager to kill without feeling, to interact with men without love. But when she's kidnapped by the enigmatic leader of a rival organization, she learns she's been lied to for years. She never worked for the good guys. Collin Ryker believes the sultry woman he's abducted knows more than she's telling about The Circle and its plans for complete domination. Over time, as they work together, Olivia's tenacity and vulnerability captivate him. But if he isn't careful, Collin will fall into the biggest trap of all: caring for a woman who can betray him to his greatest enemy.
