Coach’s Pet by Alexa Riley

Charlie kicks off her senior year of high school by getting sent to the principal’s office. Her punishment? Being the school’s mascot Bucky Beaver. She didn’t think it could get any worse… until she lands on top of the hot new football coach.
Coach Shay retired from the NFL, and now he’s got some time on his hands. When his friend asks him to take over as head coach at the high school for one year, he doesn’t hesitate. The first time he sees Charlie he realizes he’s made a mistake. His obsession is out of control, and he can’t make it stop.
