More accurately, I would give The Lost World
around 2.5 stars. I would describe this Jurassic Park
sequel as less a fiction novel and more a nonfiction work about evolution science with a few moments of fiction woven in. This work is inundated with long speeches about evolution, genetics, the anatomy of a cell, etc.--which are very informative and interesting if you forget that you're supposed to be reading a novel, but then you remember and realize that you can't necessarily take anything in this novel as educational because it's a work of fiction
and you don't know which science is real and which is made up by Crichton himself.
The plot of the novel goes something like this:
Let's go to an island and study dinosaurs.
[Evil Scientists] Let's go to an island and steal dinosaur eggs.
[Everyone] Oh no, the dinosaurs are eating us! Let's run away!

Riveting? Not so much.
