Let's start with the obvious; the TV series isn't going to win any highbrow drama awards and this book is faithful to the TV series. With that said, the series is entertaining and funny and, again, the book is faithful to that. Think Dan Brown with added dinosaurs - classic sci-fi entertainment which doesn't require much thinking.
The plot is very typical of the show although it's obviously quite a bit longer than usual and, without giving too much away, it has the usual dose of spectacular settings, nasty villains, plenty of action and, of course, dinosaurs. Abnett has done a good job of capturing the characters' personalities and traits and for the most part they ring true. Having seen them on TV makes it all the easier to visualise them, and when Connor tries yet another terrible joke you'll find yourself using his voice in your head. It all fits together very well.
As TV tie-ins go, this is a good one and should keep you entertained. The author knows his audience and what they want, and has done an excellent job of delivering it.
