Alan doesn't want to go. He was in Jurassic Park before, and he almost died there. He doesn't want to go near the place again.
But he has to have money for his work with dinosaur bones, so he says yes. But are Mr. and Mrs.Kirby really rich? Do they really like to do interesting things? Why do they really want to visit Isla Sorna?
Life get very dangerous for Alan Grant when he finds the answers to these questions.
