There is a reason Cord McAllister, a budding aeronautical genius decided to return to Boulder, Colorado. His father, also a scientist, is missing and he needs to find him. However, Boulder has been under siege by a local warlord, who has created an impregnable mountain-top citadel. How will he use his ingenuity to find a way to infiltrate the mountain fortress and rescue his father along the way?

Cord must join forces with the local sheriff and his headstrong yet enticing daughter to stop the warlord and destroy the deadly technology he has stolen, presumably from Cord's own father. If their mission fails, there is a weapon of war which could bring destruction to more than just Boulder, Colorado. The future of the entire nation, even the human race, is at stake. Will they successfully face all obstacles that separate them from the ultimate goal, bringing back peace?

Angry Comanche and embittered miners are just a few of the dangers that lie ahead in their journey. Hot air balloons, knock-out bombs, the cutting edge of the day's technology is used to mount a rescue for the ages, a harrowing and dramatic adventure that explodes across the page. Will the rescue team save the entire nation from obliteration at the hands of a madman? A must read for fans of adventurous historical fiction with a touch of romance!

"Into the Impenetrable Fortress" is a historical adventure novel of approximately 80,000 words. No cliffhangers, only pure unadulterated action.
