Book is tight and very square - new/unread. Very light wear to ends of spine of DJ - otherwise excellent.

Title page says "illustrated by Jim Cawthorn & George Barr" - the wraparound cover (which is reproduced in color on front and back endpapers) has signature by Jim Cawthorn and George Barr (upper left of back cover); the 12 full-page black & white interior illos are not signed, but look more like the work of Jim Cawthorn than George Barr. Size is 6-3/8" by 8-3/4"

[Since I haven't read this, I'm quoting from the flap copy of the Owlswick hardcover for a decent summary/setup]:
The Gods of the West decide to destroy Prince Vakar of Lorsk, a kingdom on the sinking continent of Poseidonis, lest the events wherein he is destined to play a part cause their own downfall. Warned, Prince Vakar sets out to seek the thing the gods most fear, without knowing what it is. His search takes him to Ogugia, the Isle of Philosophers. There he renews his acquaintance with the widowed Queen Porfia, until the gaffe of slaying her lover forces him to flee. In Torrutseish, capital of the Tartessian Empire and lair of the world's mightiest wizards, he learns that he must proceed to Belem, the land of headless zombies. All the while, supernatural dangers close in upon him, while his enemies back in Lorsk prepare a fatal welcome for him, should he be so lucky as to return...

[Somewhat expanded in 1953 from an original appearance in Two Complete Science Adventure Books Winter 1951.] The 1953 hardcover edtion from Twayne included 3 related stories also set in Poseidonis, but the paperback editions of 1968 and 1971 contained the novel only, as did the 1977 Owlswick Press hardcover reprint. I'm not sure if there is any edition other than the 1953 original that includes the extra stories.
