Miles is going after the people who hurt his best friend. He'd thought the shifter world was finally done with labs and doctors who experimented on them, but he was wrong, and he has every intention of fixing that. Preston just wants his best friend back. Jasper was kidnapped, and Preston knows he's being hurt. He's lucky Jasper managed to call him and that he's a decent hacker, but he's only one man. How is he supposed to break into a government lab and rescue his friend? Things get both more complicated and easier when Miles and Preston meet. Preston is horrified to find out he's the mate of a professional assassin, but Miles and his friends can give him the help he needs to break into the lab. Miles is ready to do this and much more for Preston, even if Preston decides to leave afterward. Will Preston be able to accept Miles and what he does for Jasper's sake? And if he can, what happens once Jasper is free?
