Black Sun

From Graham Brown, co-author of the "New York Times" bestselling thriller "Devil's Gate" with Clive Cussler, comes "Black Sun" . . .
In the heart of the Amazon, NRI operative Danielle Laidlaw makes an incredible discovery: a translucent Mayan stone generating massive waves of energy while counting down toward the infamous apocalyptic date: December 21, 2012. And somewhere, there are three more just like it.
What power will be unleashed if all four stones come together? Who created them--and who has them now? Using a cryptic Mayan map and a prophecy that points to the end of the world, Danielle and her team race toward answers. But one staggering question remains: Were these artifacts meant to save us--or to destroy us once and for all? "From the Paperback edition."
