The Knight's Map by R. C. Sproul is an allegory for children and is very much like the Pilgrim's Progress. Its focus is on the tale of a Knight without loyalties to any king who receives a mysterious letter, and also a map, from a King (whose existence is doubted by people), the King invites the Knight to follow the map to find a Treasure that will not fade away. The Knight encounters many obstacles along the way, mainly these obstacles take the form of the Knight being misled by other people like Mr. Skeptic and Mr. Liberal who try to draw the Knight's attention away from trying to read the map correctly (and even discouraging any attempt to read it at all).
The book has many nicely drawn (or rather, painted) pictures that I am sure would have captured my interest as a child. The story is well-written and would hold the interest of adults as well as children. There is a question and answer section at the back that could be helpful to parents in prompting their children to think about what the story represents, though I think that the actual story has enough explanation in and of itself through the dialogue of the Grandpa (who is telling the story) and his grandkids at the beginning and ending of the book.
I think that my biggest problem with this book is that I wish it were longer. It just seemed too short, even for a kids book, but perhaps that is because I am judging with an adult's brain. I think that that is a sign of a good book, when it leaves you wanting more. Perhaps someday Mr. Sproul will come up with an adult's version, one that delves into even more detail about those who want to distract us from the Bible/map that God provides us with. I find allegories like that in this book fascinating. But even if he doesn't come up with an edition for older people, this book is good in its own right, simple and straightforward picture of a person seeking God and God's provision of understanding and guidance along the way to discovering Him.
