Before reading this, I finished JURASSIC PARK, and, believe me, they both seem pretty different. Don't get me wrong, though- they're both absolutely fabulous.
This is mainly about a lost city called 'Zinj' that was a really prosperous and ancient diamond mine in the Congo. Though it had been lost for years, a sort of artifact-hunting American company used technology to find the location. They immediately form a team to go and get it before the rival company finds the diamonds first. Why are these diamonds, that are supposed to be laced with impurities, so desirable? It turns out that these so-called 'blue diamonds' is one of the key factors to the making of super fast- and expensive- computers. Whichever computer company gets these diamonds will have a monopoly on the market for about the next five years- which makes the buyers extra and specially intent ($$$$$$$$$$) to get 'em.
But, the team has a bit of a problem. The eight crew members mysteriously were murdered on-site. Video footage of the site shows that the attacker was a black figure that looks exactly like a gorilla.
And that's one of the reasons why Amy, a super-smart gorilla that knows-and has conversations- in sign language is recruited for the ride. She had recently been having nightmares of the city, because that was where her mother had been murdered- in exactly the same way that the researchers had.
So they set off for the city, prepared for whatever the monster may be...
One thing that you have to love about Crichton books is that they're so incredibly scientific. At the beginning, anything can be possible, from aliens to yetis to monsters, but in the end, the REAL scary thing is that it really seems possible. I was a total Crichton fan after reading just one of his books; they all rock, this one included. Even if you're a bit wary about reading a book that sounds so centered around a monkey, go for it. you'll be surprised.
