Play! is a delightful children’s chapter book by Barbara J. Sloan, featuring illustrations by Jarrett Rutland, which appeals to all ages. The narrative follows cousins Collins and Violet as they are taken on magical time-travel adventures by Professor Dante Marlowe Browne. With him, they learn about theatre history and playgoing manners. Their journeys span various historical periods from Ancient Greece to the Victorian era—demonstrating how audience etiquette has evolved. The work culminates with the trio attending a performance of Peter Pan at the modern-day Sizzlepop Theatre, reinforced by a final list of Professor Browne’s Playgoing Manners.
