The book starts with an unnamed
black cat investigating the run-down former living quarters of the
wizard Merlin of
Arthurian legend with the implied intent of trying to find something worth stealing. While there she meets a
northern spotted owl who takes her through the house and explains Merlin's life, magical abilities, and what the book describes as 'The
Pendragon Alchemy', a
philosophy of life that says that giving nets greater rewards, both monetary and emotional, than taking. The book tells of Merlin protecting an unnamed princess from a cadre of evil sorcerers (and in the process creating a
ring of stones in
Avebury), and falling in love with
Nimue, the
Lady of the Lake, described as being a water
sprite princess. It is revealed that the black cat is Nimue and the owl is Merlin. The couple return to their natural forms and resume their love affair. Nimue steals Merlin's
Wand in order to give it to the evil sorcerers to free them. Initially believing she could save the magical world with their help, is eventually deceived. When she realizes her mistake, she attempts to use the wand against the sorcerers. However, Merlin, misunderstanding her intentions, steps in and is struck by a bolt from the wand, imprisoning him magically. In his final act, Merlin transforms Nimue into the water of a nearby lake, close to the cave where he remains trapped. They are fated to be confined, yet in proximity, until 'the seeker' (the reader) solves 'the spell' (the puzzle's solution), thereby summoning the wand as the ultimate reward. ==Puzzle and solution==
