Congo contains introduction and references.

Deep in the heart of the Congo, near the legendary ruins ofthe Lost City of Zinj, an eight-person field expedition dies mysteriously and brutally in a matter of minutes. Ten thousand miles away, in Houston, Karen Ross watches a gruesome video transmission of that ill-fated team: a camp destroyed, tents crushed and torn, and the grainy, moving image of a dark, blurred shape. In San Francisco, Amy, an extraordinary gorilla with a 620 "sign" vocabulary and a fondness for finger painting, has recently drawn a replica ofthe frayed, brittle pages of a portuguese print dating back to 1642, a drawing of the ancient lost city. Immediately, a new expedition is sent into the Congo, descending into a secret world where the only way out may be through the grislest death.
