Turning For Home by Caren J. Werlinger

Like her mother before her, Jules Calhoon couldn't wait to escape her small Ohio town. Unlike her mother, though, Jules couldn't disappear forever. When she's called back for her grandfather's funeral, the visit unleashes a flood of memories and starts her on a lonely-and familiar-path. Her partner, Kelli, feels Jules slipping away but can't figure out how to pull her back. In desperation, she turns to Jules's oldest friend-and her ex-Donna. The problem is, Donna never could figure out why her relationship with Jules ended so long ago, and she never stopped loving Jules. When a lonely, confused teenager reaches out to Jules for help, the past and present are set on a collision course, igniting a chain of events that will leave none of them unscathed.
