Femme by Mette Bach
Academics have never been Sofie's strong point; she's too busy spending all of her free time with her boyfriend, Paul, the captain of her high school's soccer team. When her English teacher implements a new program that pairs her with straight-A student Clea, Sofie worries about how Paul will react to her hanging out with the only openly lesbian girl at school. Sofie is as surprised as Paul at how close she and Clea quickly become.
When Sofie discovers that Clea is planning a road trip to check out some colleges over the winter break, she invites herself along, causing more issues with Paul. It's only after a college student asks if Sofie identifies as a "femme" lesbian that she starts to question her own sexuality and her relationship with both Clea and Paul.
