About This Book
The sharp snap of a crocodile’s jaws echoes in Rachel’s ears, but it’s not just a sound—it’s her own wild morphing out of control. From the tiny tickle of an ant’s legs to the heavy thud of an elephant’s footsteps, her body shifts wildly without warning. With every unexpected change, the stakes rise higher, and Rachel feels the weight of a secret that could put them all in danger.
Quick Assessment
This middle-grade science fiction novel follows Rachel as she struggles with uncontrollable morphing abilities, including allergic reactions that complicate her transformations. The story explores themes of self-control and friendship within a fantasy setting, suitable for ages 9-12. Parents should be aware of mild peril and fantastical violence, typical for the genre.
