fiction novel with arthurian elements and references.
Coney, Michael Greatrex, Fang, the Gnome. (Signet/New American

Galahad - with the other characters appearing only in "the Game"

alternate reality and influence the characters there. Eventually the

becomes a reality.

Cooper, Susan, Over Sea, Under Stone, The Dark Is Rising, The Green

Lancelot and Guinevere are, in various forms, called back to assist in

the tale is steeped in Celtic mythology and part of the fun is
matching characters back to specific myths and legends.
