Prions, the CDC, a stolen Mayan codex, a race to stop an epidemic and the approaching date of 12/21/12 make for a heart pounding novel and a fun summertime read. A cross between a Robin Cook/Michael Crichton medical/biological thriller and a Clive Cussler/James Rollins action/adventure novel, it combines the best of both in an intelligently written book that takes the reader on a journey from the lab to the museum to the jungle. From the land of the ancient Maya to present day Los Angeles there is little chance for boredom and a great chance that the reader will spend time worrying about the truth behind this original story.
