In true Crichton-esque style, this is one part education in genetic research and practices, and one part warning about the things that have gone or may go wrong. As usually, it all ends with the author's note which summarize his fears and points out how much wrong has already been done by gene patenting practice.

In a court case in the book, a judge rules that the genetic research company which bought cell tissue from a cancer survivor, OWNS the cells. That leads to the absurd situation in which the genetic company loses the sample cells, then pursues the donor to replace what's loss, since the cells are ruled their property. Even more bizarre, when they can't find the original patient, they pursue his daughter and grandson, who are "in possession of stolen property", i.e. they inherited grandfather's cells. Spooky.

Sadly, such unexpected twists are few and far between. Mostly we are bombarded with weird cases of genetic research, patenting and scandalous experiments on wildlife. There are too many storylines, few of which never come to conclusion, and few others never intersect. The main characters, human and animal, are so numerous, they are hard to follow. There are hybrids - and I'm not talking about cars, but rather products of crosses between human and animal DNAs. The ones I can't quite swallow are the talking orangutan and chimp. A shorter, more focused and more action-packed story would, to my opinion, better emphasize the author's concerns.
