A trio of pulse-pounding thrillers from the USA Today–bestselling author and "one of the best all-out action writers in the business" ( Los Angeles Review of Books).   "Nobody writes action like Jon Land," and in these three edge-of-your-seat international thrillers, the stakes have never been higher (John Lescroart). No wonder James Rollins says: "Jon Land proves yet again that suspense has a new king."   The Valhalla Testament: After his sister—an American undercover operative masquerading as a journalist in Nicaragua—is murdered and he is imprisoned, NFL running back Jamie Skylar must escape to the United States to warn the government of an impending terrorist attack.   Vortex: Vietnam special-forces veteran Joshua Bane must wage a one-man war to stop a government conspiracy from completing a superweapon that could alter the very fabric of reality. Project Vortex would make the atom bomb look like a bow and arrow—and push the world into a devastating global conflict.   The Doomsday Spiral: An Israeli special-forces operative whose true identity is buried under so many layers of deception that not even the Mossad knows who he really is, Alabaster may be all that stands between a terrorist plot targeting the US and total oblivion.
