Wall of Serpents

The premise is that mythology and great works of fiction are really discriptions of alternate universes. The hero of a series of books by Fletcher Pratt and L. Sprague DeCamp learns how to travel to the alternate universes. The Wall of Serpents is set in the world of Irish myth. The authors are great story-tellers and this series works very well. The sword fights, battles of magic, and battles of wit are all delightful. The reader will find this book more enjoyable if it is read after The Compleat Enchanter.

The author's names for _Wall of Serpents_ areL. Sprague de Camp and Fletcher Pratt(not L. Sprague and Fletcher Pratt de Camp).I havne't read this one yet as it is out of print, but I just finished _The Compleat Enchanter_ by the same two authors and containing the initial (mis)adventures of the same characters, which was such good fun that I am interested in tracking down this sequel! Well written, and with a delightfully intelligent sense of humor.
