Fall From Grace by Candace Wondrak

Wren was never a girl who liked to make mistakes. Up until the day she found her boyfriend in bed with her best friend, that was, and then everything changed. She lost it all: her hope, her dreams, and especially her will to sing.
But life goes on, and she decides to take life by the balls. Have fun. Make some mistakes that she surely won’t regret…
What does taking life by the balls mean? For her, it means meeting a brooding, handsome stranger at the club and going home with him with the intent of never seeing him again. Giving him a part of herself she never gave anyone before.
It all goes great… except that handsome stranger she met at the club turns out to be a newly-enrolled student at her college with a killer voice—and she’s pretty sure he’s hiding something big. To get him to open up to her, she’ll have to face her own aversion to singing to draw the truth out of him.
Can Wren find her voice again, or will her heart lead her to ruin?
