"Greetings from the dead," Maxwell Broadbent declared from the videotape he left behind after his mysterious disappearance. A notorious treasure hunter and tomb robber, Maxwell accumulated a priceless collection of rare art, gems, and artifacts before vanishing completely-- along with all his riches.

At first, robbery is suspected, but the truth proves far stranger: as a final challenge to his three sons, Maxwell has buried himself and his treasures somewhere in the world, hidden away like an ancient Egyptian pharaoh. If his sons wish to claim their inheritance, they must find their father's concealed tomb.

Furthermore, Maxwell's priceless possessions include a codex-an ancient Mayan manuscript that contains all the lost arts of Mayan herbal medicine, secrets that will revolutionize pharmacology. The codex is worth billions, and one pharmaceutical company CEO has sent mercenaries after it with orders to kill anyone in their way, including the beautiful and enigmatic woman accompanying one of the sons.

Now the race is on, but the three brothers are not the only ones competing for the treasure. Others soon join the hunt--and some of them will stop at nothing to claim the grave goods.
