Last year the inaugural Tucson Festival of Books had almost 50,000 attendees. This annual event showcases local authors, libraries, bookstores and other literary-related organizations, and benefits local community literacy providers. In addition to almost 200 exhibitors, this event is also a huge writers' convention with lots of talks, panels and workshops from national authors etc.
And it's free!! It's on next weekend, March 13-14th, at the University of Arizona between 9.30 and 5.30 both days.
I'll be manning the Tucson Romance Writers of America booth (#116 along University Blvd, subject to change) on Sunday 2-4 pm and giving away ARCs (uncorrected bound galleys with full color cover - almost the real thing!) of Song of Scarabaeus to interested readers.
