Another (2025) by Paul Tremblay is his very first middle-grade horror after several fabulous adult novels with equally dark themes. This one follows a troubled middle schooler named Casey whose parents are beguiled by a strange man who arranges an even stranger sleepover between our protagonist and another boy who is new in town. As the days pass, this new friend starts to seem a little too familiar. Casey must find a way to reach his parents in their dazed compliance with the strange man's strange rules and make everything go back to normal by remembering what makes him Casey.
