A Perfect Wreck by Aria Cole

He’s the all-American upstanding boy-next-door, she’s the fearless loudmouth with looks that could break any boy’s heart.
One kiss and Asa stops seeing Callie as his sister’s best-friend. Instead he can’t forget her mouth or stop imagining all the things he’d like to do to her.
When Asa enlists and fights overseas, Callie works just as hard at home to accomplish her dreams.
A wounded war vet will be her most difficult case.
It doesn’t help that he’s the same boy who stole her heart, and was the very first to taste her lips.
