This is the 14th book in Terry C. Johnston's Plainsmen series, published in 1999. This one is about the outbreak of the Nez Perce War of 1877 leading to the Battle of White Bird Canyon, the first clash between the Nez Perce warriors and the US Cavalry. It's a wild ride as Johnston throws us right into the action from the start and the fast pace never lets up (and we're talking about 429 pages leading to the Afterward). The story focusses on a huge cast of characters, Nez Perce and white military personnel and civilians. All were actual people and Johnston had to make educated guesses about their thinking, that is, why they made the decisions that they did and behaved as they did.
What I'm most impressed by is this author's attention to detail and authenticity. No one is writing better historical fiction set in the West. I also appreciate the author's Afterward. A bibliography of non-fiction books about the Nez Perce and the conflict of 1877 in the Northwest is included.
Sadly, as I understand from Goodreads, Terry C. Johnston passed away, in 2001. "Cries from the Earth" is the first book of what Johnston intended to be a trilogy within his Plainsmen series. The follow-up book is "Lay the Mountains Low," published in 2000. After that, Johnston died, so I believe he did not finish his Nez Perce trilogy. Perhaps some reader out there can correct me on that.
