Aside from the obvious puns about how this was the Next book I was going to read, and that my wife was going to read it Next....
So this was one of the least enjoyable Michael Crichton books out there.
All about genetics, genetically modifying organisms, gene editing, gene therapy, etcetera.
Crichton comes off kinda heavy handed and preachy in this one. Although I enjoyed learning a lot about genetics (see, that's what you get from reading Crichton-- you learn about stuff without realizing it), the story was really fragmented. It's like the author had lots of okay ideas about stories involving genetics, but no real good ideas, so he just mixed them all together.
One thing this book suffered from is lack of any real good guys. Nearly every character was slimy, underhanded, despicable, or weak in some way. Part of me wonders if this is a deliberate way for Crichton to get his readers to involuntarily dislike genetic engineering, but based on his diatribes (spelled out awfully clearly in-text, and even more deliberately in the afterword), he's not opposed to genetic engineering, and in fact, thinks it's the wave of the future.
Anyway, some of the sci-fi stuff was a little out there (a human-chimpanzee hybrid that we're supposed to sympathize with?), but I guess I shouldn't rag on this book too much. After all, it was a fun, quick read, and I learned stuff.
...but if you're looking for a good Crichton book to start with, this is not it. Instead I'd recommend Sphere, Congo, Jurassic Park, Andromeda Strain, Prey.
