When you don't have a lot of time to read and need something to at least past the time while you are getting from point A to point B (usually sitting in an airport), a novella fills the bill nicely. Here is one I read recently that is worth a look: A Soldier's Heart by Tamara Lynn Kraft. It is actually #13 in a series called Murray Pura's American Civil War Series.
Kraft is from Ohio and she writes with authority as she has studied and researched the historical background of the civil war and Ohio's part in it. A Soldier's Heart surprised me as I had no idea that post traumatic stress syndrome was recognized back then but that's what they called a soldier's heart. The story is one man's struggle to overcome the awful things he experienced during his service and how his family and community helped him. It is interesting reading and short enough to get you through that layover in the airport and you can get a glimpse of Ohio albeit in the days of the Civil War.
