In a spellbinding blend of history, myth, and science, best-selling novelist Manda Scott unleashes a thriller that sweeps from the secrets of the Mayans to the court of a 16th-century queen to a shattering end-times prophecy.  

"It's a lump of rock, Stella; nothing more. No stone is worth dying for."

Except it's not just a lump of rock. It's a blue crystal skull made by the Maya to save the world from ruin; a sapphire so perfect, so powerful that for centuries men have killed to own or destroy it.

Ancient prophecies say that if the 13 skulls already in existence are not reunited, the world will end on December 21, 2012. Cedric Owen, the skull's last Keeper, died so that it might keep its secret for the next four centuries. Now Stella Cody has found it, and someone has already tried to kill her. Like Owen, she's being hunted - but by whom?

Desperate to unravel the mystery of the crystal skull, Stella must decode Cedric Owen's coded writings, sketches, and ciphers no scholar has been able to unravel. What she discovers is astounding: a shocking secret prophecy...and the staggering puzzle of four terrifying creatures, 13 precious stones, and what will happen if Cedric Owen's crystal skull falls into the wrong hands. But time is against Stella. She has only days - hours - left to uncover the only secret that may yet save the world.

12.21.12. The date is set. Time is running out. The end of the world starts now.
