Her next book project will be a historical biography of a Santa Fe Trail trader, Henry O'Neill. Mary lives in New Mexico with her husband and daughter.


Irvin Hornkohl lived the life and told the stories in Just Do It, Crazy or Not. He had the wisdom to get Mary to write it all down for him. This book is his first published work.

Irvin lived with his wife on a Colorado ranch. He passed away in 2016 at the age of 92.











Irvin and Mary working together on the book. Mary and Irvin spent three years putting this book together. Mary recorded more than fifty hours of Irvin telling his stories. She then transcribed the stories, often pulling bits and pieces of the same story from different recordings. She gave the stories shape and cohesion, editing and adding details for clarity. Mary and Irvin met by chance on an airplane when they sat next to each other. They met on December 7, 2006, the 65th anniversary of the Pearl Harbor attack.
