Relic: Douglas Preston and Lincoln Child

I really enjoyed this book until the very end. The story starts on an expedition years ago in South America where some scientists are looking for answers about a lost tribe. The entire expedition dies, but the loot makes it back to the United States. Oddly enough everyone on the boat that brings the goods into New Orleans is missing. We come to modern day in the Chicago Natural History Museum where people begin to be disturbingly murdered. The Hypothalamus glad is removed from each of the victims. This begins to happen as the museum is planning for a "superstitions" exhibit. We find out there is a monster living in the museum that was feeding off of the packing material from the ill-fated expedition in South America, and once the crate was moved the monster finds the hypothalamus has the same hormones as its primary food source. I was enjoying the story at this point, there have been references that it was similar to Jurassic Park, and I did agree with that. The ending however loses me. We are to believe this Monster boarded the ship with the boxes the scientists packed and then wandered to Chicago from New Orleans without being seen. Then we find out that the monster is actually one of the scientists from the expedition that ate a plant which had a virus and turned him into this "super being". The story was interesting and a fast-paced read.
