Crazy in Love by Dawn McClure

Having gone through foster care on the hard streets of Chicago, Logan Byrne has no clue what family is, let alone what it means. He joined the Marine Corps at the age of eighteen to belong to a brotherhood, and now four years later, he’s up for re-enlistment. Having nothing and no one outside of the Corps, he’s ready to sign on the dotted line. That is, until he meets his best friend’s sister.
Katie Smith is well aware that Logan is completely out of her league. Guys like him don’t give girls like her a second look. And yet, when she meets him in person, all of her common sense and rationale immediately pack their bags, leaving nothing behind but hormones and bad choices—and that’s exactly what Logan would be. She’d never have thought an innocent weekend together on her family’s farm would change her mind—or her heart.
