Twilight of the Fifth Sun — David Sakmyster

Amid the ruins of Ancient Mexico, a prophecy predicts the end of the Fifth Sun, the universal destruction of our own time. While recovering from a vicious attack on her life and returning from the brink of death, Rebecca gains the ability to see the ghosts and spirits found all around us. This power brings her to the defense of a boy with the miraculous ability to free the earthbound souls. The child is hunted by the ghost of the most blood-thirsty ruler in Aztec history-an evil power driven by an ancient prophecy to conquer both the living and the dead and to bring about the end of our age. With a cast of complex and entertaining characters, the story races to a furious climax atop the pyramids of an ancient Mayan city, where the battle for the salvation of the world will be waged. One of the most gripping books I have ever read. Spooky, terrifying, heart-pounding fun. -Mark Morgan
