Roach - bookseller, loner and true crime fanatic - is not interested in making friends. She has all the company she needs in her serial killer books, murder podcasts and her pet snail, Bleep. That is, until Laura joins the bookshop. With her cute literary tote bags and sunny smile, she's everyone's favourite bookseller.

But beneath the shiny veneer, Roach senses a darkness within Laura, the same darkness Roach possesses. And as curiosity blooms into morbid obsession, Roach becomes determined to be a part of Laura's story - whether Laura wants her in it or not.
