More than 100,000 people are expected to visit campus as the popular annual event makes its return. New this year: a scavenger hunt for kids that will be available in English and Spanish. "There is so very much to look forward to," says Welz Kauffman, Tucson Festival of Books executive director. "Great authors and books, terrific moderators, so much for kids and families to do, plus a variety of things to eat and drink, wonderful music, and a powerful volunteer contingent ready to answer questions and welcome a diverse crowd."
