What if your worst nightmare was the only thing you wanted? Lydia worries she'll never recover from a violent assault at the hands of an intruder. Therapy isn't working and her friends aren't a comfort. All she can think about is how helpless and afraid she was. Then she meets Isaac. He's everything she wants to be: cool, calm and controlled. Trauma doesn't seem to affect him. Emotions don't bother him. And best of all, he's prepared to teach her. He shows her how to fight. How to defend herself. How to guard her heart. But Isaac soon finds he can't guard his heart from her. She's starting to make him see all the things he's been missing, in his closed off and far too brutal life. The only problem is: He has a terrible secret. And if he lets himself give in to the desire that's building between them, her world may well be torn apart again.
