The Gardner School of Arts and Sciences is hosting its annual Book Swap from 10 a.m. to 1 p.m. Oct. 13. The event is open to everyone, whether enrolled or not. Attendees should bring a selection of gently used books of all genres for all ages. Each attendee can choose up to 10 “new to them” books to take home. Attendees need not bring books to take books. The school is also accepting well-worn books for recycling and repurposing. While on campus, guests are encouraged to explore the school grounds, including the wetlands, garden and playground.
