Sign up for the Tween Book Club (ages 8-13) and get a free copy of the graphic novel “Mighty Jack” by Ben Hatke! Read the book before the event and then bring it to the book club on August 4. Join a librarian and other tweens at the event to discuss the graphic novel. After the book discussion, enjoy a related activity with an LARPD Open Space Park Ranger. Space is limited, so registration is required. Call 925-373-5505 to register.
