In my Crooked Arrow Ranch series I do deal with death and PTSD. The series is about disabled veterans who have come home and the VA can’t help them so they move to a special ranch in Montana that cares only for disabled veterans. I’m a disabled veteran so i’ve drawn upon my own experieces as well as those of my friends. I did have an ancilary character commit suicide. Not in the book, but his sister spoke a little bit about it. She was the main female character.
