This is simply one of the best historical fiction reads I've picked up in a long, long time.
My 13-year-old son loved it!
For one thing, the MC is younger, and infinitely easier for students to relate to, as he behaves as a kiddo - wanting to fight and help support his mother, even after losing a brother in battle, entering the military by lying about his age, playing his bugle, wanting fiercely to go home and circumnavigating the rules whenever he can.
Here's the response from the author, Michael Shoulders:
"I'm in the process in creating one along with my wife who is a middle school English teacher."
When it's available, I'll post about it, and provide the link, in For Educators. I'm really looking forward to spreading the word about this book!
