David Wood and Stephan Pastis, two of the authors in the Star Pavilion at the Tucson Festival of Books, March 9-10, will be online at live.azstarnet.com chatting with readers today and Friday.
• Noon today: Wood, of the Huffington Post, spent eight months on his Pulitzer Prize-winning "Beyond the Battlefield" series on the severely wounded of Iraq and Afghanistan.
• 1 p.m. Friday: Stephan Pastis, author of the comic strip "Pearls Before Swine," in which his sweet, simple drawings belie the cartoon's complexity and edgy themes. He has a children's book, "Timmy Failure: Mistakes Were Made."
Go to live.azstarnet.com to take part in either - or both - chats. The chats are also available on the Star's mobile and iPad apps.
