Corrie ten Boom is one of my favorite authors. Her style is exceedingly simplistic and so easy to understand. She uses every-day analogies that help to cement her stories and bring them to mind during normal activities.
Corrie ten Boom lived in the Netherlands during WW2 and she, along with her family, were very involved with working with the underground networks and hiding a handful of Jews, and supplying transportation, ration cards, and homes for countless others. Although this book doesn't talk about that, it does touch on her years in concentration camps and then often mentions forgiveness and how their story helped others as they traveled around.
The book is actually a transcript of devotionals she shared on the radio, so it reads very much like a chat, with mentions of the people who are listening and on the other side of the radio. It was unique in that way and made it seem more personal.
Like all of Corrie's books, this one had great insight and was told in a compelling manner. I didn't agree with 100% of it, but I still recommend it and look forward to re-reading it in the future.
