Save the date for our next YO! BookFest: Saturday, October 24, 2026

The YOung People’s Book Festival of Greater Philadelphia (YO! Book Fest) is a free event featuring some of the nation’s most beloved authors and illustrators of children’s, middle grade, and young adult books. YO! Book Fest is a celebration of writing and reading created from a community partnership of Children’s Book World (Haverford, PA) and Black Rock Middle School of Lower Merion School District (Villanova, PA).

Join us for interactive author and illustrator sessions, book character photo ops, cozy story times, book crafts, book sales and signings, and more. Proceeds from book sales at YO! Book Fest benefit Bringing Books to Life, LLC, a nonprofit organization that brings authors and books to under-resourced schools in the greater Philadelphia area.

Matt Phelan, Mike Ciccatello, and John Patrick Green demonstrate how to illustrate in front of a group of children.
