The book was well written and he gives people a lot to think about. However, I think it was very misleading for many people who will erroneously assume that they can wait until they are in a coma before they face up to their shortcomings and get right with God. This is not to say that God couldn't do this if He wanted to, but it is highly unlikely.
It is a very entertaining book, but with a couple of changes at the end, the author could have made it much more scripturely sound. An indidividual has to make knowing choices to achieve salvation. I liked the "The Shack" and recommended it to a number of people. Not this time.
I found the book to be an enjoyable read---for a work of fiction. Young offered some interesting ideas and personifications of the triune God.
I feel that some portions of the story where lifted from C.S. Lewis' "The Great Divorce," but it was different enough not to make too much fuss over.
I know that Young had to make one of the characters unlikeable, but he did such a good job that I never really got attached to him. When he encounters difficult situations, I didn't feel a great deal of sympathy for him.
Overall, it was an enjoyable escape from reality with a few ideas that make the reader contemplate non-traditional concepts, but nothing I would consider groundbreaking or theology shaking.
This book was not quite as incredible as The Shack but similarly gives insight as to the massive variety of ways in which God works in us, uses us to work in others, loves us into his care and pursues us for his Kingdom purposes!
