Steve Irwin, Animal Planet's "Crocodile Hunter", and his wife/co-star Terri, bring their wildlife adventures to book form, and it works pretty well.
The hardback book has excellent production value - glossy pages and loads of color photos. Very niuce, and informative if you don't know what a perentie looks like.
Steve's persona on tv - that of the highly excitable wildman who picks up venomous snakes and wrestles gigantic crocodiles - is no act. He describes it as merely having an enthusiasm for wildlife, and that enthusiasm is contagious. The book tells of how he developed this love of animals (basically, he was raised with it). Terri tells of how they met and fell head over heels in love at first sight. On their first date, Steve told her "You're not at all ladylike!" (which he meant as a compliment, it's sweet, in a weird way).
Neither of the Irwins are particularly stylish writers. The phrase "passion for wildlife" is repeated often, making the text occasionally sound repetetive, though not insincere. Still, both are gifted storytellers. Just like their tv show, the book draws you in to their world. You feel like you're right there with them trying to save a giant reptile that's trying to rip you apart.
If the book has a shortcoming (aside from the minor fact that some of the tales will be familiar to regular viewers of the tv show) it's that it is too short. Steve does impart a good deal of knowledge about his beloved wildlife, but could have explained more. For example, he tells that apex predators like crocodiles are key to the health of an ecosystem - true, but he doesn't elaborate on why. Terri tells informative and fascinating anecdotes about caring for a wide variety of creatures at the Australia Zoo. I wanted more of those.
Overall, the book does a good job in its primary mission: making you interested in animals, so that you'll care enough to try to fight for their survival.
