I just discovered FireFighter Nation.  I worked as a wildland firefighter for ten years before I began writing a mystery series based on fire investigation, that has been popular with fire professionals and outdoorsmen.  In fact, a friend of mine who teaches fire investigation sells the books at his courses.  I do a lot of research with police, forensics techs, and arson investigators, like Steensland.  Trying not to sound like a salesman here, but if you work in fire or arson investigation, you'll probably like these books.  The first two books are titled 'Day into Night' and 'One Careless Moment'.  They're published in Canada, but are available on Amazon.  I'm also looking for interesting wildfire arson stories, for more books in the series, so feel free to send me a note, here or through the contact at my website at www.davehugelschaffer.com. ; Stay safe.
