Emma Carpenter lives in isolation with her golden retriever, Laika, house-sitting an old beachfront home on the rainy Washington coast. Her only human contact is her enigmatic old neighbor, Deek, and (via text) the house’s owner, Jules. One day, she reads a poorly written --- but gruesome --- horror novel by H. G. Kane and posts a one-star review that drags her into an online argument with none other than the author himself. Soon after, disturbing incidents start to occur at night. To Emma, this can’t just be a coincidence. Could he be stalking her? When Emma digs into Kane’s life and work, she learns that he has published 16 other novels, all similarly sadistic tales of stalking and murder. But who is he? How did he find her? And what else is he capable of?

As her twin’s final hours come into focus, Lena’s search turns into a harrowing tooth-and-nail fight for her own survival --- one that will test everything she thought she knew about her sister and herself.
