With the life he's led and the muscles he's gained, Armie Jacobson isn't afraid of anything. Except maybe Merissa Colter's effect on him. It's not just that she's his best friend's little sister. Fact is, she deserves better. Women pursue him for one night of pleasure, and that's all he wants to offer. Until rescuing Merissa from a robbery leads to the most erotic encounter of his life. Good girl meets bad boy. It's a story that rarely ends well. But Merissa is taking matters into her own hands. No matter how he views himself, the Armie she knows is brave, honorable and completely loyal. And as past demons and present-day danger collide, they're both about to learn what's truly worth fighting for...
