Mattel Press, working with Simon & Schuster, has announced three upcoming children’s book series for summer 2027: a Rock ’Em Sock ’Em Robots graphic novel, a middle-grade series about young witches, and illustrated Chatty Cathy adventures. The books are available to preorder, but the supplied report does not list their publication dates, prices or preorder links.
Mattel Press has announced three new children’s book series being developed with Simon & Schuster, including a Rock ’Em Sock ’Em Robots graphic novel, a middle-grade story about five young witches, and illustrated adventures featuring Chatty Cathy. The announcement expands Mattel Press’s upcoming young-reader lineup, and all three books are available to preorder, according to The Toy Book’s report.
The Rock ’Em Sock ’Em Robots series begins with We’re Gonna Need a Bigger Bot, written by Dustin Brady. The graphic novel follows the creators of Blue Bomber and Red Rocker as they compete to take control of Downs Town, using inventions and increasingly outlandish tactics against one another. The source describes it as intended for children ages five and up. A second title in the series is scheduled for spring 2028.
Jen Calonita is writing Moonspell School for Witches, a middle-grade series about five girls taking part in the Witch Trials to learn whether they will be admitted to a legendary magical school. The publisher’s description, as relayed by The Toy Book, says each girl brings different strengths to the trials and that the group discovers the value of working together. The series is aimed at older tweens; its next book is planned for fall 2028.
The third series is Chatty Cathy and Planet Silent, by Rebecca Elliott. Cathy Chatterson travels with her friends Benjamin Pinkles and Mr. Bulky to a quiet planet where they encounter a creature called the Silence Beast. The story turns Cathy’s talkativeness—something that has caused her trouble—into a potential advantage. Further books are scheduled for October 2027 and spring 2028, though the report does not provide titles for those installments.
Three Properties, Three Reader Groups
The announcement brings together three distinct formats and age ranges under one publishing slate: an early-reader graphic novel tied to a familiar toy property, a fantasy series for older tweens, and illustrated stories centered on a classic character. That variety may help families and booksellers identify titles for different readers, while connecting Mattel-owned characters and concepts with children’s publishing.
The initial books also establish a longer schedule rather than a one-off release announcement. The report identifies follow-up installments extending into 2028, giving readers an indication that each project is planned as a series. However, the available information does not establish how many books each series will contain or whether the announced follow-ups will be the next installments in every case.
For caregivers, the age guidance is specific only for the Rock ’Em Sock ’Em Robots graphic novel, listed for ages five and up. The other descriptions use broad audience labels—middle grade and older tweens—rather than exact age ranges. Families choosing books should check the eventual publisher listings for more detailed age and reading-level guidance.

Mattel Press Builds Its Book Slate
The three projects were announced by Mattel Press, the publishing imprint working in partnership with Simon & Schuster, according to The Toy Book. The source presents them as part of the imprint’s upcoming young-reader lineup and reports that preorders are open. It directs readers to Simon & Schuster’s website for additional information.
The series use different approaches to familiar storytelling ingredients. The robot book adapts the competitive premise of Rock ’Em Sock ’Em Robots into a comic adventure; Moonspell School for Witches centers on friendship and cooperation during magical trials; and the Chatty Cathy story uses a journey to a soundless planet to make its heroine’s talkative nature part of the plot. These are descriptions of the announced premises, not independent assessments of the books’ content or reception.
The announcement names authors and planned follow-up windows, but the supplied report does not state firm release dates for the three initial books. Its headline and article framing place the titles in the summer 2027 lineup, while the specific later dates apply to subsequent books: October 2027 for a Chatty Cathy installment, spring 2028 for follow-ups to the robot and Chatty Cathy series, and fall 2028 for Moonspell School for Witches.
“The graphic novel is intended for kids aged five and up.”

Release Dates and Book Details
The supplied report does not give exact publication dates for the three initial titles, beyond placing them in the summer 2027 lineup. It also does not list prices, page counts, formats beyond the Rock ’Em Sock ’Em Robots graphic novel, or the preorder links for individual books. The report says all three are available to preorder but does not provide order totals or details about distribution.
It remains unclear how many books are planned for each series, whether the announced 2027 and 2028 follow-ups have final titles, and whether the listed windows could change. The age descriptions for Moonspell School for Witches and Chatty Cathy and Planet Silent are also less exact than the stated five-and-up audience for the robot graphic novel. No independent information about the books’ final manuscripts or reception is included.
Preorders and Later Installments
Readers can check Simon & Schuster’s website for further information and preorder availability, as directed by The Toy Book. The next milestones identified in the report are the initial summer 2027 releases, followed by a Chatty Cathy book in October 2027. Planned follow-ups then extend to spring 2028 for Rock ’Em Sock ’Em Robots and Chatty Cathy, and fall 2028 for Moonspell School for Witches.
Further publisher listings may supply exact on-sale dates, pricing, formats, age recommendations and fuller descriptions. Until those details are published, the timing beyond the broad seasonal windows should be treated as a plan reported in the announcement, not a precise release calendar.
