My brothers best friend

Hazel, her brother Eli, and his best friend Lucas, have been the closet of pals since you can remember. They spent their summer together doing stupid shit like sneaking into illegal clubs, and getting caught, or road trips somewhere in the northern part of California. Nothing could possibly ruin Hazels relationship with her practical brother. Except for maybe a drunken one night stand... Now she can't seem to stay away no matter how hard they try.
