Query: Great Read

Turn Back Time is a captivating story of survival in mining communities during the Depression, a well-drawn picture of what the miners and their families endured under uncaring management and how they coped. The characters are so well done, so well developed, you feel like part of the family from early in the book. The plot flows well and the pacing is such that you'll find it hard to put the book down, despite the fact it's well past your bedtime. While there is trauma and emotion, there is also humor throughout the book. I hated to see it end. I highly recommend you add this to you Kindle collection.
