Book #7 in the Sigma Force series (2012)
Deep in the Rocky Mountains, a gruesome discovery — hundreds of mummified bodies — stir international attention and fervent controversy. Despite doubts to the bodies’ origins, the local Native American Heritage Commission lays claim to the prehistoric remains, along with the strange artifacts found in the same cavern: gold plates inscribed with an unfathomable script.
During a riot at the dig site, an anthropologist dies horribly: burned to ash in a fiery explosion in plain view of television cameras. All evidence points to a radical group of Native Americans, including one agitator, a teenage firebrand who escapes with a vital clue to the murder and calls on the one person who might help: her uncle, Painter Crowe, director of Sigma Force.
To protect his niece and uncover the truth, Painter will ignite a war across the nation’s most powerful intelligence agencies. Yet, an even greater threat looms as events in the Rocky Mountains have set in motion a frightening chain reaction, a geological meltdown that threatens the entire western half of the U.S.
