In Bump, by Matt Wallace, twelve-year-old MJ is bullied, grieving, and a little bored. Her former gymnastics teammates still pick on her. She loves her mom, but misses her dad and the home they used to share with him. And with her mom working all the time and taking classes, MJ spends a lot of time alone and in her own head. A chance encounter changes her life and leads to her pursuing...nay...actively fighting for the opportunity to train at a wrestling school. There, MJ finds the community she wasn't aware she was looking for. When outside forces threaten her new friends and home-away-from-home, MJ takes leaps she never expected.
