Cassandra Ramos-Gomez’s Don’t Wake Up Brings El Cucuy to a New Generation

Don't Wake Up (The Doll Island Series #2) by Cassandra Ramos-Gomez moves its young heroes from the aftermath of one frightening encounter into a new supernatural danger. At 156 pages, the Simon and Schuster book, listed for 2026 at $19, offers a short, direct horror adventure for readers in grades 3–7. Reviewer Michelle in the Middle recommends it as optional reading, with appeal to several kinds of readers.

A familiar group faces a new threat

Eleven-year-old Diego and his friends Jandro and Itzel have grown closer since their frightening experience on Doll Island, near Mexico City. Their friendship gives the story a ready-made center: these are kids who have already faced something disturbing together, and now they have to decide what to do when danger reaches their school.

Classmates begin falling asleep and slipping into comas. Diego, Jandro and Itzel connect the crisis to El Cucuy, a demon who takes the souls of sleeping children. Their goal is clear: save their classmates. The title signals the unnerving condition of the threat, since El Cucuy wants everyone to stay asleep. That premise gives the book a simple, immediate source of suspense that younger horror readers can follow without a complicated setup.

The review identifies the trio as Mexican and singles out the book’s cultural elements, along with its interplay of English and Spanish. Those features give the adventure texture beyond the supernatural danger. For readers who enjoy seeing characters’ language and cultural background woven into a story, that mix is a particular draw. The review doesn’t describe specific scenes or language choices, so it’s best to let the book’s own pages show how those elements appear.

Horror at a manageable scale

Michelle’s assessment is measured: the plot is fairly simple, but the level of horror feels right for grades 3–7. That combination may suit readers who want a spooky premise and a clear rescue mission without a long, demanding read. The stated content ratings are G for language, with zero swears, G for mature content, and G for violence. Those ratings, alongside the reviewer’s age-range guidance, can help families and educators judge whether the book fits a particular reader.

There’s a practical pleasure in the length, too. At 156 pages, Don't Wake Up offers a contained entry point for readers who might be drawn to scary stories but are not looking for a substantial novel. A concise page count can also keep the central danger in view: the friends have a defined problem, a supernatural cause to confront and classmates to protect.

That streamlined approach has a trade-off. Readers seeking a densely layered plot may find the story’s simplicity less satisfying. But for its intended age range, a direct storyline can make room for atmosphere, friendship and the tension of trying to wake people from a perilous sleep. Michelle’s praise for the book’s horror level is specifically her judgment; the right amount of fear will vary from reader to reader.

A sequel that leaves room for more

The book is the second in The Doll Island Series, so Diego and his friends arrive with a shared history. The review gives the essential context—a frightening earlier experience on Doll Island—without requiring readers to know more about that story to understand the new threat. Readers who like returning to a familiar group may enjoy watching the three friends meet another challenge together, while those new to the series have a clear starting point for the present conflict.

Michelle says the ending wraps up adequately while setting up the next book. That gives this installment a degree of closure alongside a reason to continue: the immediate story reaches a stopping point, and the series remains open for another adventure. The review doesn’t disclose what the setup involves, leaving that discovery to the reader.

For readers choosing a school-age horror title, Don't Wake Up looks best suited to those who want a brisk supernatural story, a close-knit trio and cultural details that include English and Spanish. Its premise is easy to grasp, its length is approachable, and its danger is calibrated for grades 3–7 according to the reviewer. The next question for series readers is what new trouble Diego, Jandro and Itzel will face after they confront El Cucuy.
