Sergeant Kellan O'Ryan. Soldier. Assassin. Beast. Working covert ops as ordered. Living a black and white existence. Until everything shattered into grey and nothing made sense anymore. An anomaly on the species scale, Kellan's world was one of cold precision and stoic duty. A world he believed to be his own but when the beautiful Detective Charlotte Alistair stormed into his life, it shook the foundations of all that he was and believed himself to be. Initially wary of her, Kellan soon found himself ensnared in a way he didn't think was possible. She enthralled him, captivated his every sense, human and animal alike. She revealed pieces of himself he didn't know existed and a life he had forgotten. But how? What happened to him? At first, amnesia seemed to be the only explanation but as he began to unravel the truth it soon became clear that nothing was as it seemed. The more he learned, the less he knew. And with nothing but his gut instinct to guide him, he needed to keep his focus sharp and clear even as his feelings for the beguiling cop began to dominate his every moment. With Charlotte and his alleged best friend, Finn McGregor now crowding his once solitary existence, the danger threatening him came not only from unseen enemies but from within. Because the more he opened his heart, the more he risked. Would the connection he felt with Charlotte be the strength he needed to survive the upheaval or would it be his weakness?
