Few things are as terrifying as changing from the inside out.
Body horror is one of the most unsettling corners of the horror genre because it takes something familiar, our own bodies, and turns it into something frightening. These stories explore transformation, infection, mutation, obsession, and the terrifying possibility that the thing we trust most can become something we no longer recognize.
From grotesque physical changes to unsettling questions about identity and humanity, these thirteen books deliver nightmares that linger long after the final page.
Welcome to "Under the Skin" books for the Body Horror prompt in the Scaredy Cat Reading Challenge: a year-round horror reading challenge designed to help readers discover every corner of the horror genre.
