Crazier, even more philosophical sequel to Jurassic Park. Kind of reminded me of how Larry Niven wrote the second Ringworld book to correct the errors in the physics implied in the first book. Improbably brings Ian Malcom back from his fate in Jurassic Park. Once again the mischievous children save the day, while the adults are acting like children. The Levine character was the most insufferable; I hoped he would be eaten. There were lots of excellent & gory dinosaur eatings. Some of the discussion of the Anthropocene extinction was kind of ahead of its time. I read this book many years ago (without having read Jurassic Park), but all I remembered about it from then was the explanation of what prions are, & the speculation about the Velociraptors missing the Velociraptor “culture” that allowed them to thrive back in the Cretaceous. I don't understand why they went through the trouble of bringing powerful poison darts with them for protetion on the dinosaur island, while not even bothering to pack so much as a 9mm handgun (which is after all, good enough for the cosmonauts worried about bears, wolves and tigers of Siberia eating them when they come back from orbit). I was appalled by the characters' shoddy communication arrangements. Who arranges for a helicopter pick-up without having a means of radioing the helicopter? And Levine really should have at least sent Malcom or Thorne a postcard or voicemail giving some indication of where he was going & what he was doing. Was this just an illustration of pre-cell phone society's cavalier “we'll meet if we meet” attitude towards staying in touch with friends & potential traveling companions?
