Author of the Day

Chadwick Wall
Chadwick Wall has written for the New Orleans Times-Picayune, the Sewanee Purple, the Riverside Reader, the Baton Rouge Advocate, and most recently Austin.com. After years living in many cities and regions, he counts himself lucky enough to reside in the laid-back yet vibrant, friendly and creative city of Austin. Here he spends many of his days and nights either holed up like a hermit, reading or writing away-or prowling around, investigating all of the live music, delicious cuisine, and cultural hotspots he can find. As our Author of the Day, Chad tells us all about his latest book, The Second Cortez.
