Tomorrow's Magic by Pamela F. Service

This story takes place 500 years after the nuclear holocaust that destroyed the earth's population. Wellington Jones and Heather McKenna are both two students who go to a British boarding school, basically in the middle of nowhere. Thy befriend a somewhat troubled boy named Earl . Earl seems like an ordinary guy that has lost his memory, but he is the opposite. Earl is really the well known 2000 year old wizard Merlin. The trio discover this after Earl gets hit rather hard in the head. They go on many adventures (that are too good to reveal) on their mission to create a much better society. This seems like an easy thing to do, but not with Morgan Le Fay foiling all their plans. This book is not yet published, but will be on April 28, 2007. I loved it and I recommend it to all teens and even some people ages 10 and up. These books were originally published in the 1980's, and this is Service's "new" version of them.
