Caverns of Socrates

Book excerpt: They called themselves the Black Foxes, a group of adventure gamers whose chosen transformations formed a group of superior powers: a pathfinder, a master healer, a magical bard, a Shadowmaster, and their leader, an extraordinary warrior. The Black Foxes are chosen to test Avery, an incredibly powerful artificial intelligence -powerful enough to create a virtual reality universe so convincing that the Black Foxes would forget the outside world. But a delicate balance is easily destroyed, and control over Avery is lost. Now the Black Foxes must carry out a dangerous quest and defeat a Demonqueen -their only hope for survival is to beat Avery at its own deadly game.
