The Return of Kukulkan — Malcom Massey

Storm clouds gather as 2012 dawns across the mysterious land of the Maya. Beneath the ruins of Chichen-Itza lie unrevealed Mayan artifacts that promise profit and power to those bold enough to acquire them. Ominous events in the skies threaten Martin Culver's team of archaeologists and astronomers, as ancient enemies square off against each other on the ground. Old friendships and new alliances strain under the pressures of an unprecedented peril that even Earth's foremost experts have been unable to resolve. Will the secrets of a key Mayan Prophecy be revealed before time runs out? The answer, known only to one living person, lies hidden with The Lost Calendar of the Maya.
