Dainese Santos and Celia Lee at Simon and Schuster have acquired the middle grade horror Lost on Doll Island by debut author Cassandra Ramos-Gomez, about eleven-year-old Diego who is sent to live with his tíos in Mexico City and will do anything to get his old life back—even search for a wish-granting doll hidden on the notoriously haunted Isla de las Muñecas. Publication is planned for fall 2025; Sandra Proudman at Gallt and Zacker Literary Agency negotiated the deal for world rights.
