Join us for our Greenwich Book Festival Finale with Robin Stevens and Cressida Cowell. Robin Stevens, author of the brilliant ‘Murder Most Unladylike’ series and winner of the Waterstones Children’s Book Prize, will be joining us to talk about mysteries—unladylike and otherwise—at a very special event at Greenwich Theatre. She'll be on at 11:30 a.m. and will be singing books afterwards. Cressida Cowell, author of the amazing "How to Train Your Dragon" series and the "Wizards of Once" series, follows Robin Stevens at 2:30 p.m. Cressida will talk about her latest book, "The Wizards of Once: Twice Magic," as well as her work on "How to Train Your Dragon", her inspiration and give tips on becoming an author or illustrator. You can buy tickets for each event, or get a special ticket that covers both events. For more information, go to www.greenwichbookfest.com
