Unruly by Landry Hill

He’s been locked away for six years. She was just a kid when he went inside.

But now… she’s all grown up, and he is no longer her sweet and innocent stepbrother.
He isn’t the boy with the charming smile who felt the need to please everyone.
He’s Dark, Dangerous, and Unruly.
Knox now has only one need. HER.
And with the thoughts running through his head, it’s a good thing he’s locked behind bars.
One look at his sweet stepsister and he’s just become a criminal.
