Yield

Meet the men of Savage Security: They protect your body, you must protect your heart.
Meet Adam Savage ex-military Navy Seal. He lost his heart while serving as a Navy Seal in Afghanistan. He came home and survived by throwing himself into the family business. Ignoring the trauma and PTSD he carried inside. Feeling nothing until he met Cassie Sheng. One look at the beautiful IT expert his brother hired, and he found the heartbeat he thought he'd lost. For six months she shared her body and soul. Her warmth melting the arctic tundra inside. Eight months later it was over. No explanation, other than a pitiful Dear John letter.
He'd sworn he would forget about her. He'd lost so many people already, he knew how to lose one more. But then mysterious events at Savage Security put her back on his radar. Three years later and he's not sure if she's here to hurt him or help him. The only thing he does know for sure, is that he's not walking away again. Not without answers.

Cassie Sheng gave more than her body when she shared her bed with Adam. But he'd never given as much as he took. She left their entanglement after eight months. Eight months of taking her body and ignoring her heart. And now three years later he's asking for answers she doesn't have. Breaking her heart again by accusing her of betraying Savage Security. Tearing down the walls she built up to protect herself. But this time, he won't get her heart without giving his own.

Although Yield is a standalone book set in the world of Savage Security it is best enjoyed after reading the first 3 books in the series. It contains no cliffhangers, no cheating, and a guaranteed HEA.
