I'm Matthew Kerns, author of Texas Jack: America's First Cowboy Star which was just released yesterday. Because of Reddit's support, my book hit #3 on Amazon's Western US History New Releases. AMA.
A picture of me holding my book pre-release inexplicably blew up over on r/pics the other day, and the outflowing of support from reddit helped my book do way better on release than I expected. This book, and most of what I've written lately, is centered around the American "Wild West" period just following the Civil War. My book is about the first famous cowboy, Texas Jack, and the ways in which his real-life adventures became the foundation of later cowboy tropes and myths in pop culture.
If you have questions about the Wild West, my writing process, when Half-Life 3 might be out, or the smooth sophistication of Steely Dan, let me know. I'm happy to answer, or try to answer, all questions.
