DA VINCI CODE meets TOMB RAIDER in this award-winning thriller that #1 NYT bestselling author James Rollins called, "A book that defines 'page-turner.'"
Spain 1057: During a thunderous battle, the first King of Aragon wrestles Alexander the Great's priceless Egyptian weapon from the Moors, but finds it holds a terrifying and mysterious power.
Nearly a thousand years later, on a fog-shrouded Napa Valley morning, gunshots rip through the silence. Maddy Marshall, an app designer with special martial-arts abilities, and her twin brother quickly run toward the sound. Horrified, they discover a sniper has cut down two members of their family.
Before the pool of blood on the living room floor is dry, their father sends the twins on a dangerous quest to recover Alexander's ancient weapon. Joined by a broad-shouldered marine who harbors a secret alliance, they soon discover the lethal sniper is from Russia.
They follow time-worn clues to a lost warren under the streets of Jerusalem, racing to unlock the secrets that will lead them to an arcane power--before a hostile state seizes it and cripples the United States.
To survive, they must go undercover and off-grid. Because now, the sniper has his sights set on them.
