1 bestselling authors Doug Preston and Lincoln Child return with their next blockbuster Pendergast novel

A long-buried family secret resurfaces when one of Aloysius Pendergast s most implacable enemies shows up on his doorstep as a murdered corpse. The mystery has all the hallmarks of the perfect murder, save for an enigmatic clue: a piece of turquoise lodged in the stomach of the deceased. The gem leads Pendergast to an abandoned mine on the shore of California s desolate Salton Sea, which in turn propels him on a journey of discovery deep into his family s sinister past. But Pendergast learns there is more at work than a ghastly episode of family history. He is soon being stalked by a subtle killer bent on vengeance over an ancient transgression. In short order, Pendergast is caught in a wickedly clever plot, which will leave him stricken in mind and body and may well end with his death.
