Map of Bones (Sigma Force)

The bones lead to ancient mysteries and present-day terror . . . To follow them means death.

During a crowded service at a cathedral in Germany, armed intruders in monks' robes unleash a nightmare of blood and destruction. But the killers have not come for gold; they seek a more valuable prize: the bones of the Magi who once paid homage to a newborn savior . . . a treasure that could reshape the world.

With the Vatican in turmoil, Sigma Force under the command of Grayson Pierce leaps into action, pursuing a deadly mystery that weaves through sites of the Seven Wonders of the World and ends at the doorstep of an ancient, mystical, and terrifying secret order. For there are those with dark plans for the stolen sacred remains that will alter the future of humankind . . . when science and religion unite to unleash a horror not seen since the beginning of time.
