17-year-old vegan feminist Ellen Lopez-Rourke has one muggy Houston summer left before college. She plans to spend every last moment with her two best friends before they go off to the opposite ends of Texas for school. But when Ellen is grounded for the entire summer by her (sometimes) evil stepmother, all her plans are thrown out the window. Determined to do something with her time, Ellen (with the help of BFF Melissa) convinces her parents to let her join the local muggle Quidditch team. An all-gender, full-contact game, Quidditch isn't quite what Ellen expects. There's no flying, no magic, just a bunch of scrappy players holding PVC pipe between their legs and throwing dodgeballs. Suddenly Ellen is thrown into the very different world of sports: her life is all practices, training, and running with a group of Harry Potter fans. Even as Melissa pulls away to pursue new relationships and their other BFF Xiumiao seems more interested in moving on from high school (and from Ellen), Ellen is steadily finding a place among her teammates. Maybe Quidditch is where she belongs. But with her home life and friend troubles quickly spinning out of control—Ellen must fight for the future that she wants, now she's playing for keeps.
