Valhalla

Along the Greenland ice cap, an expedition team makes an astounding discovery. Buried five hundred feet below the ice cap is the wreckage of an ancient ship—and nine perfectly preserved Vikings. Rune markings indicate it went missing in 1016 BC. Energized by the find, retired Air Force general Steven Macaulay assembles the foremost scholars of Norse archaeology, including Harvard academic and master decoder Lexy Vaughan. But the mission is violently sabotaged—because this discovery holds the key to a mystery that will change the human race. To put together the pieces of the puzzle, Macaulay and Lexy plunge headlong into a web of chaos and betrayal—all the while hunted by a covert primeval society that will stop at nothing to protect their secrets.
