Merlin and the woods of time

"It's a perfect day in Camelot. The Table is Round and the Grail is Holy. Knights joust and Ladies show favour. Blood is spilt, love declared, and medieval pundits talk us through the action. What could possibly go wrong? But then a humble water-carrier falls head-over-heels for an arrogant beauty and in his passion stumbles on the Secret of Controlling Time. Now the survival of the world is in his hands, and it will take more than the wisdom of Merlin to save Old England from catastrophe."--P. [4] of cover.
