It began with a collision.Not in the sense of souls colliding or even stars aligning, but in a real-life, totally her fault, bumpers-crunching, frames-bending, airbags-deploying crash.Haley. Oh Haley.Why was she such a mess?And why did she have to be such a mess when it involved really expensive cars and really handsome men? She was an emergency room nurse. She was supposed to have it all together, to be cool under pressure, to be-Not turned into a complete puddle of mush when it came to the man whose car she'd crunched.But Sam was so . . . so nice and sweet and gorgeous and he made Haley's brain just completely poof out of her skull. But Sam was also her past.Or rather, her sister's past.She couldn't be attracted to the person who'd broken her sister's heart. She couldn't want him. It didn't matter that a decade had passed. Plus, Sam had never noticed her before. Haley was the little sister, the annoying tagalong. Sam wasn't attracted to her and he never would be.But what if maybe . . . just maybe that colliding of bumpers had finally knocked some sense into Sam?What if he decided Haley wasn't the annoying little tagalong sister anymore? And what if she gave into the temptation incarnate of all her childhood fantasies? And worse what was Haley going to do if her sister found out?
