PLEASE NOTE TIME AND DATE CHANGE Internationally bestselling, critically-acclaimed British fantasy author Sir Terry Pratchett will discuss his upcoming 37th Discworld novel, “Unseen Academicals,” during the next free Authors @ the Teague talk and signing at 10 a.m. on Tuesday, Sept. 8 in the City Hall Council Chambers next to Velma Teague Branch Library, 7010 N. 58th Ave. Over 60 million copies of his books for adults and children have been sold in 37 languages, and 2008 marked the 25th anniversary of his long-running and much-beloved satirical Discworld series. Pratchett has received numerous honors and awards, including the 2001 Carnegie Medal for an outstanding book for children and young adult readers, a Printz honor book for young adult literature, several honorary doctorates, multiple Locus awards for science fiction and fantasy writing, the L.A. Times Book Prize, and a knighthood. Recently diagnosed with early-onset PCA, a rare variant of Alzheimer’s disease, he has become an influential advocate, donating one million dollars to the Alzheimer’s Research Trust. Since “Unseen Academicals” will not be released until October, other Discworld books will be available for purchase and signing. Because of time constraints and audience size, signing will be limited to one to two items, signature-only, with no personalization. Parking will be available in the downtown parking structure at 58th Dr. and Palmaire Ave. Pratchett’s appearance is made possible by the North American Discworld Convention in Tempe on Labor Day weekend. For more information about the convention, go to http://www.nadwcon.org. Seating will be on a first-come, first-served basis. Due to travel and health issues, this event may be subject to change, rescheduling or cancellation. Call 623-930-3431 to confirm or for more information.
