The Other Brother by Kristen Granata

Every choice has a consequence.
Charlotte Thompson knows it all too well. On the run from her past, she hopes to start over in her new home. To keep her secret safe, she must avoid getting close to anyone. The last thing she wants is to get involved with the town’s notorious bad boy.
Tanner Brooks is forever doomed to live in the shadow of his older sibling. Regarded as troubled and brooding, he’s seen as nothing more than the other brother. That all changes when a striking new girl captures Tanner’s attention. Charlotte gives him something to feel other than heartache and rage. Determined to prove himself, he will do anything for her … even if it means putting his life on the line.
Between Tanner’s unwavering pursuit and Charlotte’s wavering defenses, sparks fly. But when Charlotte’s past catches up to her, she is forced to face the consequences of her actions. What’s worse, Tanner is taken along for the ride. Charlotte needs to save Tanner from her mess and keep them both alive.
