Girl in the Walls by A.J. Gnuse
I requested this on Netgalley based entirely on the title.
Elise is an orphan who lives in the walls of the house where the Eddie and Marshall live with their parents. The boys know that there’s something in the house besides their family, but their parents don’t take them seriously. Elise has managed to live there for ages, moving through the house by climbing down the spaces inside the walls. But as time goes on, the boys become more and more convinced that there’s something/someone there and Elise meets the local boy Brody, who keeps her secret and becomes her friend.
And then things start to unravel.
This book is literary in style and beautifully written. I cared so deeply about the children that I stayed up until 2am reading it, so that I knew they were safe. There are some genuinely scary bits. I absolutely adored the book.
Thank you to the publisher and Netgalley for the review copy.
