I was really intrigued by the time travel aspect of the book as well as the historical fiction. The whole other side was very interesting and I loved the scenes that happened there between Kelsey and his guide, Leavitt. Kelsey was also an amazing and well developed character: brave and determined, he has pain hidden deep inside, is a self-described ass-hole, but would do anything to help another member of his team. This made him perfect to go back to the Civil War. One thing that threw me though was the changing point of view between Kelsey and Garrity, an officer in the Dragoons where Kelsey first awakes in 1861. I wasn't really expecting so much of the book to focus on someone else, especially so soon. For much of the book the perspectives are taken back and forth between Kelsey's experience and Garrity's. This does have a purpose in the end, but at first it was a little disorienting. Anyhow, the context into the Civil War with a view from each side was very detailed and graphic. Much of the battles, prison conditions and medical treatment was done with historical accuracy. The ending was inspiring and surprising, nothing that I saw coming.
This book was received for free in return for an honest review.
