Crushing Little Things by Amy Meitz

Juliette Valentine is a cunning, complex, and pathological child prodigy. At just fourteen years old this elite gymnast manages to weaponize the family dog, create a rabies panic in her small town, initiate a CPS investigation into her own mother, and successfully hunt, capture, trap, and tame Jonathon, the boy next door. The reader will get to know both Juliette and Jonathon through their own unique perspectives and by way of various flashbacks of their traumatic childhoods.
