A mesmerizing and suspenseful coming-of-age novel about an orphan hiding within the walls of her former family home—and about what it means to be truly seen after becoming lost in life. Eventually, every hidden thing is found. Elise knows every inch of the house. She knows which boards will creak. She knows where the gaps are in the walls. She knows which parts can take her in, hide her away. It’s home, after all. The home her parents made for her, before they were taken from her in a car crash. And home is where you stay, no matter what. Eddie is a teenager trying to forget about the girl he sometimes sees out of the corner of his eye. But when his hotheaded older brother senses her, too, they are faced with the question of how to get rid of someone they aren’t sure even exists. And as they try to cast her out, they unwittingly bring an unexpected and far more real threat to their doorstep. Written with grace and enormous heart, Girl in the Walls is a novel about carrying on through grief, forging unconventional friendships, and realizing, little by little, that we don’t need to fear what we do not understand.
