Back Under The Stairs - Book 2 in The Bandworld Series
by John Stockmyer
John Lyon was able to make it home from the first trip to Bandworld unscathed. His 20th Century knowledge now buttressed by the magic he'd learned to use in the alternate world ... what could be wrong with taking another trip to enchantment-land? Nothing. . . If you don't count John's encounter with the Lxlop, being caged by Pfnaravin, and a deadly battle with the Azare Mage-King Auro!
