That Thing You Do by Juliana Stone

All her life, tomboy Molly Malone, has been one of the guys. When her brother decides to get married it means the gang will reunite, but more importantly it means Nate Jacobs will finally come home. With the impending nuptials looming fast and a family that can barely put together a grocery list, Molly will be tested like never before. To make matters worse, one look from Nate confirms he’s still her kryptonite and that her teenage crush is now something more. He’s only ever thought of her as ‘one of the boys’ and to protect her heart, she’s determined to keep it that way.

At thirty years of age, sports agent Nate Jacobs has got it all. Dream job, nice home, expensive car, and all the eye candy he can handle. But lately he’s realized something is missing. He just doesn’t know what it is. So, coming home to Crystal Lake for his buddy’s wedding is a welcome distraction. He can kick back, relax and get his head on straight. The only problem? Molly Malone. She’s still the pain in the ass she always was, so why is he thinking things he shouldn’t be? Like kissing her? Like what is underneath those baggy jeans? She’s also acting weird and that makes him wonder, what the hell is she hiding?
