Corrupting His Good Girl by Cass Kincaid

Vienna Anderson was Garrison High’s good girl—valedictorian, scholarships, and a mouth that couldn’t even utter a curse word.
She was also Cohen Bradley’s everything. His high school sweetheart, his first love…and the one that got away.
One stupid mistake on prom night, and he lost her. Not a word, not a glimpse.
For ten years.
Then, she crashed into him—literally—tilting Cohen’s world on its axis, making his body ache with need, and giving his heart a reason to beat again.
But with Vienna back in town, details about that fateful night that ruined them start to resurface. Suddenly, they both have questions, and neither of them are prepared for the answers. But one thing is certain…
Nothing is what it seems. Nothing, except the undeniable attraction that still lingers between them, a smoldering desire that not even a decade apart could extinguish.
Cohen lost Vienna once, and he won’t let it happen again. Even if it means revealing secrets that may have been better off buried, and falling in love all over again with a woman who may not be as sweet and innocent as she once was.
