Hell's Pavement — Anthony Pryor

The road to hell is paved with good intentions... and with the bones of those foolish enough to go there. The Ravenglass Fragment is in the hands of a madman and his crazed followers. Only Dr. Naomi Johar knows the location of the last fragment, which unlocks the keys to ultimate arcane power -- and she's been kidnapped. Now, with time running out and their companions missing, Alex St. John and Mia Jordan must pursue the conspiracy alone. In the charnel labyrinth beneath the luxurious homes of Lake Oswego, they confront a race of cannibalistic humanoids and their leader, the fanatic neo-fascist author Gordon P. Chandler. Even Alex's enchanted sword and Mia's psychic abilities may not be enough to save them, but right now they're fresh out of options.
