Compared to other books in the series, this one doesn't stand up. When finished, you're left wanting more. This time around, dinosaur involvement is almost none. In my opinion, the transition that one of the characters has from being jovial too, well, not when put in the crisis of being lost in the desert should not have happend; it would've made the time of them being lost more interesting. Very, very little action in this one folks. It's a good read if you have the time, but prepare to be disapointed.
