There’s Someone Inside Your House by Stephanie Perkins fits perfectly in the young adult horror genre. The first chapter throws the reader right into the horror theme with all the suspense and intensity that a horror story should have. I finished the first chapter with my heart in my throat! The intensity continues from there as the suspense and suspicion grow. I read this book straight through and I would turn around and read it again. Highly recommended for horror and thriller fans-5 stars!
