Mattel Press, working with Simon & Schuster, has announced three new children’s book series: a Rock ’Em Sock ’Em Robots graphic novel, a middle-grade fantasy about young witches, and an illustrated Chatty Cathy adventure. The books are available to preorder, but the source report does not provide their exact summer 2027 publication dates or prices.
Mattel Press, in partnership with Simon & Schuster, has announced three children’s book series with lead titles planned for summer 2027. The lineup adapts the Rock ’Em Sock ’Em Robots and Chatty Cathy properties and introduces Moonspell School for Witches, giving young readers three different formats and genres to choose from; all three books are available to preorder, according to The Toy Book.
The announced titles are We’re Gonna Need a Bigger Bot, the first graphic novel in a Rock ’Em Sock ’Em Robots series; Moonspell School for Witches, a middle-grade fantasy by Jen Calonita; and Chatty Cathy and Planet Silent, an illustrated adventure by Rebecca Elliot. The Toy Book reported the announcement, citing Mattel Press, and said the books can be preordered through the publisher’s retail channels.
In Dustin Brady’s graphic novel, two independent creators build Blue Bomber and Red Rocker while competing to take control of Downs Town. Their attempts to outdo one another involve unusual inventions and comic battles. The book is intended for children ages 5 and up, and a second series title is scheduled for spring 2028, according to the report.
Calonita’s Moonspell School for Witches follows five girls taking part in Witch Trials to determine whether they can attend a legendary magical school. The story’s description emphasizes teamwork, friendship and each character’s individual strengths; the series is aimed at older tweens, with another book planned for fall 2028. In Elliot’s Chatty Cathy and Planet Silent, Cathy Chatterson travels with Benjamin Pinkles and Mr. Bulky to a quiet planet where they encounter a Silence Beast. Further books in that series are scheduled for October 2027 and spring 2028, The Toy Book reported.
Three Properties, Three Reading Formats
The announcement brings familiar Mattel properties into publishing while also adding an original fantasy series to the slate. For families, the lineup spans a graphic novel for younger readers, a middle-grade story for older tweens, and an illustrated adventure. That range may help readers compare the books by age suitability and format rather than treating the announcement as one uniform release.
The publication plans also extend beyond the first books. The reported follow-ups run from October 2027 through fall 2028, indicating that Mattel Press and Simon & Schuster are presenting these as continuing series, not isolated titles. Those dates give readers an early sense of the planned schedule, although they do not confirm final publication dates or how many books each series will contain.
Because the books are based on well-known toy and character properties, the releases also show how Mattel is using its brands in children’s publishing. The source does not provide sales forecasts, print runs, or information about how the titles will be promoted, so the commercial reach of the announcement cannot yet be gauged.

A Publishing Partnership Behind the Slate
Mattel Press is the publishing imprint named in the announcement, and Simon & Schuster is its partner for the three upcoming series. The report describes the books as part of the young readers category. It does not specify the imprint’s broader publishing schedule or whether these titles are part of a larger agreement between the companies.
The three stories take different approaches to their source material. Rock ’Em Sock ’Em Robots centers on inventors and comic competition, while Chatty Cathy’s story turns the character’s talkative nature into part of the adventure. Moonspell School for Witches is a fantasy about five girls and their shared trials, rather than an adaptation of one of the two named toy properties. These descriptions come from the announcement as reported by The Toy Book; readers will need the books themselves for full plot details.
The report says all three titles are available to preorder and directs readers to Simon & Schuster’s website for more information. It does not list retail prices, formats beyond the described graphic novel and illustrated book, or specific release days for the first titles.
Release Dates and Editions Pending
The source report gives summer 2027 as the broad window for the three lead titles, but it does not state a separate publication date for each book. It also does not identify the exact preorder retailers, prices, page counts, ISBNs, or whether editions will be available in digital or audio formats. Those details may be added to publisher listings, but they are not confirmed in the report.
The follow-up timing is more specific for some books: Chatty Cathy series titles are listed for October 2027 and spring 2028, the next Rock ’Em Sock ’Em Robots title for spring 2028, and the next Moonspell School for Witches book for fall 2028. The report does not name those later titles or establish whether the schedules are final. No publication dates beyond the seasons or month given are stated.
Preorders and Publication Timelines
Readers can preorder the three announced books now, according to The Toy Book. Simon & Schuster’s website is identified in the report as a place to learn more; further publisher listings could provide prices, formats and exact release dates as publication approaches. The report does not say when those details will be added.
The next milestones named are the lead books’ planned summer 2027 release, followed by the Chatty Cathy series’ October 2027 installment. Spring 2028 titles are planned for both Rock ’Em Sock ’Em Robots and Chatty Cathy, with a further Moonspell School for Witches book listed for fall 2028. These are the schedules reported in the announcement, and readers should look for publisher updates for any changes or additional specifics.
