Publication history.
This is a sequel to Andre Norton's 1978 novel "Quag Keep", the first novel based on a role-playing game.
Reception.
A reviewer from "Publishers Weekly" calls the book a "serviceable sequel to Norton's "Quag Keep"", and comments: "For the most part, the story and characters lack the magic and imagination typical of the late SF Grand Master Norton at her best. While unrestricted by the gaming conventions of its predecessor, this remains stock fantasy that will appeal primarily to young readers and newcomers to the genre."
"Kirkus Reviews" called it "Derivative, stale rubbish."
