Lizzie Brandt was valedictorian of her high school class, but at Radleigh University, all she’s acing are partying and hooking up with the wrong guys. But all that changes when her parents are killed in a tragic accident, making her guardian to her two younger brothers. To keep them out of foster care, she’ll have to fix up her image, her life, and her GPA—fast. Too bad the only person on campus she can go to for help is her humorless, pedantic Byzantine History TA, Connor Lawson, who isn’t exactly Lizzie’s biggest fan.
But Connor surprises her. Not only is he a great tutor, but he’s also a pretty great babysitter. And chauffeur. And listener. And he understands exactly what it’s like to be on your own before you’re ready. Before long, Lizzie realizes having a responsible-adult type around has its perks… and that she’d like to do some rather irresponsible (but considerably adult) things with him as well. Good thing he’s not the kind of guy who’d ever reciprocate.
Until he does.
Until they turn into far more than teacher and student.
Until the relationship that helped put their lives back together threatens everything they both have left.
