The Monster Marshals, a secret government agency, has been formed to protect the world from misbehaving monsters using the procedural acronym NECK, or Neutralize, Extract, Capture, or Kill. This time agent Aria Peirce and Jim Underwood have been sent to a mine in North Idaho, where an apparent AHOOL -- a giant bat or winged primate usually found in the South American jungle, has been discovered. How did it get there? And how will they battle this strange monster 5,900 feet below the surface of the earth? To do so, they'll have to call on more than just the gadgets provided by Wonderly, the Marshals' tech-savvy weapons specialist, or the angry oversite of their boss, Professor Erich Leifsson. The agents will have to rely on their own wits and those of the miners who guide them, and Aria Peirce will have to face one of her greatest fears. This tense paranormal fantasy and action thriller will keep you sitting on the edge of your seat with the lights on until you turn the very last page.
