The book The Crystal Cave by Mary Stewart tells of the life of Merlin the Enchanter from when he was six to about 24. His adventures are vividly described, whether its roaming the tunnels under his grandfathers castle or sneaking his uncle into the fortress of Cornwall. There is almost never a dull moment in this book. It takes awhile getting started, but it gets interesting around page 50, so hang in there. One part of the book I really enjoyed was when 13 year old Merlin takes a ride in the forest with his servant and catches his tutor up to no good. Overall, I'd say this book is excellent literature because it really describes everything. You can picture every scene and character in your head. I really felt like I knew each character and was genuinely upset when one died and outraged when one betrayed another. The book also teaches you a lot about the Middle Ages. There were castles, knights, maidens in distress, and all the usual stuff, but it also told about normal people. It tells of everyday life in medieval times. If you like this book, I recommend you read the 2nd and 3rd books in the Merlin Trilogy, The Hollow Hills, and The Last Enchantment. Both are just as good as The Crystal Cave. If you are fascinated with the legend of Arthur and Merlin, and are a patient reader who likes long, detailed novels like I do, you will adore this book!
