root-book

Ava Hidalgo is a perfectly normal sixteen-year-old girl: she''''s five foot four, a hundred and thirty pounds, and really, really loves getting in fistfights with boys who are bigger than her. One day, after getting suspended from school and befriending a stray cat, she gets stung by a genetically-engineered parasite and introduced to a world of danger and adventure unlike anything she''''s ever known.
