This book is absolutely the best alternate present book I've ever read. Magic is Real, and always has been, and is now a subject at Cambridge university! Rauol is a t-shirt clad teacher with new-fangled ideas of using computers to make spells quicker and easier to cast. He's a *very* lovable main character... eccentric, individualistic- e.g. he lives in a huge manor dubbed Thornhold, and hangs out at a less than reputable pub filled with less than reputable people.
Even though this book's plot is very much that of a fast-paced, exciting mystery novel, all the wonderful little details really make the people, places, and magic come alive. It gives a great idea of what things might have been like, had Merlin had an apprentice all those years ago...
