The white man killed a million American Indians. It only takes one to get even.

When a top-secret weapon goes missing on Colonel Maggie Black's watch, her honor and her career are on the line. There were airmen who said the Air Force's best female combat pilot would never be the same after losing her arm in Iraq, but state-of-the-art prosthetics have made Maggie better than new, and she's not about to lose what she battled so hard to regain.

But finding her experimental missile won't be easy --- thanks to the revenge-fueled ambitions of Asdrubal Torres, whose hallucinatory encounter with the Great Spirit challenges him to refill Lake Cahuilla, the ancient inland sea that once covered much of southern California. To fulfill his blessed mission, Torres needs wizardry and weaponry, and the Great Spirit provides both: Magic, in the form of a celebrated shaman's basket returned to the tribal museum by San Diego reporter Jordan Scott; Might, in the form of Maggie Black's top-secret weapon that falls from the sky.

From that moment, it's a race against time for Maggie and Jordan, who together must stop Torres from destroying Hoover Dam --- and turning the Colorado River into a tsunami that would kill hundreds of thousands and wipe out the Southwest's water supply. In the final showdown, it's Maggie who must disarm the stolen missile's trigger --- one-handed or not --- and save the day.
