i don't know why i hadn't thought to let you folks know about this one:

Above Snakes: A Novel of Struggle and Survival on the Oregon Trail

Above Snakes is the little known story of the Utter-Van Orman wagon train and the deadliest events in the history of the Oregon Trail.

its written by my wife/partner of 40 years and just recently published. took years of research into the actual event, going over every step of each original pioneer, reading old newspaper articles, personal letters, military reports, historic documents, traveling over their route, et al. and then there was all the fact-checking into the tribes, people, firearms and tools of the era.

we're really proud of the result and it seems readers like it too (all 5-star reviews so far). available in paperback or Kindle.
