I thought this book was awful, although my son (about six at the time we read it) said he enjoyed it. I'm pretty sure that it's a dramatization of the events on the Animal Kingdom theme park's dinosaur ride (which I haven't ridden; I was pregnant when I visited that park, so I couldn't ride any "roller coaster" type rides). But I thought this book was contrived in the worst way. The characters were annoying, the "action" was non-sensical, and I just plain thought it was stupid. Of course, it's also not very long, so at least I wasn't subjected to it for more than a night or two of bedtime reading. ( )
