Mattel Press, in partnership with Simon & Schuster, has announced three children’s book series planned for summer 2027: a Rock ’Em Sock ’Em Robots graphic novel, the middle-grade fantasy series Moonspell School for Witches, and a Chatty Cathy illustrated book series. The books are available to preorder, while later installments are scheduled from spring 2028 through fall 2028.
Mattel Press, working with Simon & Schuster, has announced three children’s book series planned for summer 2027, including a graphic novel based on Rock ’Em Sock ’Em Robots, a middle-grade story about young witches and a new illustrated adventure featuring Chatty Cathy. The announcement adds upcoming children’s titles to the publisher’s schedule, and all three books are available to preorder, according to The Toy Book.
The three projects are aimed at different young-reader groups and use distinct formats. We’re Gonna Need a Bigger Bot, by Dustin Brady, launches a Rock ’Em Sock ’Em Robots graphic novel series for children aged five and up. Its story follows the creators of Blue Bomber and Red Rocker as they compete to take control of Downs Town, using inventions and other outlandish tactics that lead to comic battles. A second title in that series is scheduled for spring 2028.
Moonspell School for Witches, written by Jen Calonita, follows five young witches taking part in the Witch Trials to find out whether they will be admitted to a legendary magical school. The book’s premise centers on the characters’ different strengths and the importance of working together. The series is aimed at older tweens, and its next book is scheduled for fall 2028.
The third series begins with Rebecca Elliot’s Chatty Cathy and Planet Silent. Cathy Chatterson travels with Benjamin Pinkles and Mr. Bulky to a planet without sound, where they encounter a creature called the Silence Beast. The story turns Cathy’s talkative nature—usually a source of trouble—into a possible advantage. The Toy Book reports that further books are planned for October 2027 and spring 2028.
Mattel Adds Three Reading Choices
The announcement expands Mattel Press’s children’s publishing lineup through three approaches: a familiar toy property adapted as a graphic novel, a fantasy series built around a school and group of young witches, and a new story using the Chatty Cathy character. That range may help families and booksellers identify options for children at different reading stages, though the publisher’s description is not a substitute for reviews or information about each book’s final length and reading level.
The formats and age guidance also distinguish the titles. The Rock ’Em Sock ’Em Robots graphic novel is specifically described as intended for children five and up; Moonspell School is aimed at older tweens. The report does not give a comparable age range for the Chatty Cathy book. For caregivers choosing books, that missing detail—and the eventual editions’ reading demands—may matter as much as the series concepts.
Preorders are available ahead of publication, giving readers an opportunity to reserve the books, but the announcement does not provide detailed publication dates, prices, page counts or a full account of each series’ release plan. The reported later installments show that the publishers are planning stories beyond the initial titles, but they do not establish that every schedule is final.

Three Properties, Three Storylines
The three series combine established Mattel-associated characters or properties with separate story premises. Rock ’Em Sock ’Em Robots supplies the setting and competing robot inventors for Brady’s graphic novel. Chatty Cathy provides the lead character for Elliot’s illustrated adventure. Calonita’s Moonspell School for Witches, by contrast, is described as a fantasy about five girls facing trials to enter a magical school.
The Toy Book reported the announcement and credited Mattel Press as its source. The publishing imprint is partnering with Simon & Schuster on the books. The report says each is available to preorder and directs readers to Simon & Schuster’s website for more information. It does not identify a specific summer publication date for each first book, so summer 2027 is the stated release period rather than a confirmed day-by-day schedule.
Release Details Still Pending
The available report does not list exact publication dates for the three first books, their prices, page counts, formats beyond the described graphic novel and illustrated book, or the age guidance for Chatty Cathy and Planet Silent. It also does not say whether the reported follow-up windows are firm publication commitments or provisional targets. Those details have not been established by the source material and should not be inferred from the announcement.
No direct statements from the authors or publishers are included in the report, and there are no quoted reactions or sales expectations to assess. The announced story descriptions and schedules are attributable to the report; readers will need publisher listings or later updates for final product specifications and any schedule changes.
Watch for Dates and Book Listings
Readers can check Simon & Schuster’s website for the preorder listings and additional information about the three titles. The books are planned for summer 2027, but exact release dates were not provided in the report. The next announced installments are spread across October 2027, spring 2028 and fall 2028, depending on the series.
As publication approaches, the publishers may provide final details such as formats, prices, page counts, age recommendations and precise on-sale dates. Until then, the summer 2027 window and later-series timing remain the schedule reported by The Toy Book.
