3 stars, perhaps 2.5 if I'm feeling pessimistic.
State of Fear is a fast-paced mystery/thriller/adventure novel that comments on eco-terrorism and the political agendas surrounding climate change. The plot follows Kenner and his team (Evans, Jenniffer, Sarah, and Morton) as they work to halt a group of environmentalists from committing heinous acts intended to draw media attention to the issue of global warming.
To begin with the good, State of Fear is incredibly engaging. I began the book apprehensive, as it appears to be a classic delayed-gratification novel that forces the reader to sift through 200 pages of character development and world-building before providing any action. I was pleasantly surprised, however, that the plot mirrors that of a YA thriller rather than a Ken Follett book. In the span of ~300 pages, each major character nearly dies multiple times; truly, the majority of the novel is descriptions of how each character cheats death. Coming out of 3 nonfiction novels, I found the action to be a pleasant addition to my otherwise insipid reading streak.
Crichton also does a relatively decent job integrating science into the plot. I'll admit, there is indubitably some (a lot of) preaching, and a few of the characters function solely as mouthpieces for Crichton's scientific/political beliefs. Regardless, blending global warming and murder-mystery is a challenge, and I think it was done with relative precision here. As a science enthusiast, however, I have to acknowledge that my interest in the nonfiction elements of the book may not reflect masterful writing by Crichton, but rather my own desire to understand the complexities of climatology.
On the topic of climatology, State of Fear provides a perspective on global warming that was entirely new to me. Crichton repeatedly questions the validity of scientific claims regarding climate change. He provides graphs and footnotes that reference specific studies - an element of the novel that I relished. Throughout my education, man-made climate change has rarely been presented as anything but a certainty, so I found this argument to be both fascinating and highly uncomfortable. To me, it's important that I continually expose myself to beliefs and rationales that I disagree with. State of Fear may not have significantly altered my understanding of global warming, but it forced me to view climate as more complicated than I had previously understood, and I think that's important.
*(I have not gone through and confirmed the relevance + validity of the studies/data referenced by Crichton)
Now for the negatives...
The vast majority of the characters in State of Fear were a tad...1 dimensional. Kenner's a genius who magically comes up with statics whenever they are relevant. Every environmentalist is a bit of an idiot. Evans is a vulnerable puppy dog who never understands anything, thus empowering Crichton to insert his climate/political beliefs at regular intervals. I understand that Crichton needed to create a clear hero/villian situation in order to propel the novel's plot, but I wish the two sides were slightly more complicated. In other words, It would've been nice if Kenner's team wasn't entirely good and everyone else wasn't entirely bad. Character development can make or break a book, and State of Fear's frequent stock characters prevent it from being a 4-star book for me.
Also, from a slightly less serious perspective, I did not want to read about cannibalism. No part of me went into State of Fear thinking, "Wow, I would love to read 3 pages of humans eating other humans!" Frickin' diabolical.
I briefly mentioned this above, but we have to acknowledge how outright preachy State of Fear is. Evans as a character was literally CRAFTED so that Crichton could spend pages upon pages explaining climatology and political agendas. Personally, I wasn't incredibly turned off by the information-dumps, but at times they were poorly integrated.
Anyway, State of Fear was relatively enjoyable and interesting, but it's not a book I will likely return to or recommend fervently.
