MISTAKES WERE MADE. FRIENDSHIPS WERE DESTROYED. BUT NOW HE'S THE ONLY ONE WHO COULD HELP HER. Cassalyn Diao has made a dangerous, faceless enemy, and the only people in the world who could help her are the same ones she had abandoned six years ago. But she doesn't have a choice. Her sister is missing, her family doesn't care, and her adversary is too much for even her to take down alone. Marcus, Earl of Farnsworth, had lost his heart to the dark-haired spy years ago and still hadn't gotten it back. When she arrives at his doorstep half-dead and bleeding, he decides that he'd do anything to return her back into his arms. Whatever it takes. But they'll have to outwit their lethal opponent first, and as the clock ticks forward and the people closest to them are thrust into jeopardy, Marcus and Cassalyn find themselves in danger of losing much more than just their hearts in this game of cat-and-mouse.
