Wrong in All the Right Ways by Tiffany Brownlee - Hardcover - Teens Fiction - Romance

An attraction between foster-siblings sets fire to forbidden love in this contemporary YA debut re-imagining of Wuthering Heights.
Everything in Emma's life has always gone according to her very careful plans. But things take a turn toward the unexpected when she falls in love for the first time with the one person in the world who's off-limits–her new foster brother, the gorgeous and tormented Dylan McAndrews.

Meanwhile, Emma's AP English class is reading Wuthering Heights, and she's been assigned to mimic Bronte's style in an epistolary format. With no one to confide in, she's got a lot to write about. Emma and Dylan try to constrain their romance to the page–for fear of threatening Dylan's chances of being adopted into another home. But the strength of first love is all-consuming, and they soon get enveloped in a passionate, secretive relationship with a very uncertain outcome.
