I enjoyed this book thoroughly, and found it was structured better than Jurassic Park was - but I still like that story, the Lost World just felt longer and a little more.. whole. It had it's wonderfully built tense moments between humans and dinosaurs. But what I loved the most about it, was that the main characters were just there to learn and observe. There are a few 'theory' moments from the characters - one in particular from Ian Malcolm that I just loved. It was definitely a little bit more thought provoking than I thought it would be.
If you enjoy the movies...I'd definitely recommend picking it up. For me...I love the worlds built in both the books and movies and can't help but immerse myself.
