Have you read John Bunyan's classic book Pilgrim's Progress? Many people have begun it, but I'm guessing few have finished it. It was written over 300 years ago. It is one of the world's best-selling books. So is the Bible. Many of us have read parts of both books, but not the full monty.
If you'd like to read a modern children's version of the book, I think you'll find Chris Wright's Young Pilgrim's Progress enjoyable and much easier to read.
I'm reading it on my Kindle and have read almost a third of it over the past few days and expect that I will be able to see it through.
I wonder if Pilgrim Books has a copy? Karl? Greg?
