In San Francisco, Riley is drinking her way through a breakup and writing influencer newsletters. When Riley accidentally-on-purpose kills her ex-girlfriend’s hedgehog, she unlocks a new euphoria she must keep chasing. Her animal murders keep escalating until her past and present collide. Meanwhile, in Philadelphia, Irina is playing video games and living in the shadow of a family tragedy. She meets a masochistic drug-addicted camgirl, who gets her involved with the vicious video-sharing website, GoreTube. There is where Riley and Irina cross paths digitally, setting off a series of events threatening to reveal both of their dark secrets. Told through gripping parallel story-lines, Hedgehog is a book about the dangers of isolation and its intersection with the Internet. In this transgressive queer horror novel, sex and violence lead to the same pleasure-filled downfall.
