I am a writer known mostly for nonfiction comics, including the New York Times bestselling The Comic Book Story of Beer: The World's Favorite Beverage from 7000 BC to Today's Craft Brewing Revolution (with Mike Smith); the U.S. Constitution: A Graphic Adaptation; and The Gettysburg Address: A Graphic Adaptation. I also wrote the scifi/time travel series Epochalypse for Legendary Comics.
