Children's Book Submissions Guidelines

We are actively acquiring children’s picture books, chapter books and middle-grade fiction for our Jabberwocky imprint. We are looking for strong writers who are excited about marketing their books and building their community of readers, and whose books have something fresh to offer!

We are not accepting any unsolicited or unagented manuscripts at this time. Unfortunately, our staff can no longer handle the large volume of manuscripts that we receive on a daily basis.  We will continue to consider agented manuscripts.

Quick Reference

  • 0-2,000 words (actual digital) for picture books
  • 1,000-20,000 (actual digital) for chapter books
  • 20,000-50,000 (actual digital) for middle-grade fiction
  • we prefer email submissions in WORD
  • always include a synopsis (including the ending)
  • allow 8-12 weeks for response
