About this book

Rick Riordan meets R. L. Stine in this fast-paced debut middle grade horror packed with adventure about a Mexican American boy who starts hearing the voice of a haunted doll while visiting family in Mexico City. Diego feels trapped. He’s confined in an arm cast, stuck with his tía and tío for a week in Mexico City, and smothered with the sickening fear that he’s the one who really caused his parents’ divorce. But most of all, he’s trapped in his own secret.

Because ever since he got to Mexico City, he’s started having strange dreams of a doll calling his name. Then Diego learns of La Isla de Muñecas, an island full of legendary magic that can make children’s wishes come true. If Diego can harness the power there, maybe he could fix everything that has gone wrong in his life. So, with the help of two new friends, Diego takes a boat to the legendary island. From the moment the kids step ashore, nothing is as it seems—with dolls disappearing and reappearing in the blink of an eye. Suddenly, Diego is more trapped than ever before, and as the night goes on, he’s not sure he can escape.
