I've always had in interesting relationship with Dinotopia. I love the James Gurney artwork and all the stories and novels, even the novel series. On the other hand, I know that if it existed in real life, I would probably not believe that dinosaurs were sentient and on the same level as humans... but I enjoy reading it all the same.
Foster writes Dinotopia really well, staying true to the spirit that Gurney created of peace, friendship, respect, and benignity that was in the original stories. He also is very familiar with the workings of the country, including how most people don't speak the same language and need translators to deal with the dinosaurs. And even though, like I said, I don't know if I would treat dinosaurs like people and not animals, it seems completely reasonable to me in the flow of the book.
This story focuses mainly on Will Denison, a character from the original books, a young man who has been living on Dinotopia with his father after being shipwrecked six years before. He is a Skybax rider, but is still learning a lot about Dinotopia and his place in it. On the eve of a terrible "six-year storm" (like a hurricane that hits the island every 6 years,) a ship of pirates miraculously lands off the north coast. They begin exploring and are quickly caught up in dreams of riches to be made from catching the exotic dinosaurs living there. When a struthiomimus family is captured, the Dinotopians are alerted, but it is Will, Chaz the proceratops, and one of the struthies who rushes into the Rainy Basin to rescue them.
I really enjoyed this story, even though it is a bit predictable. The characters are simplistic but not stupid; everything they do makes sense to them, but they are a little flat. Dinotopians=good, pirates=bad, for example, unless they are interested in science and knowledge, of course. Will is pretty much the same as he ever was, and the struthies don't get much attention, but I liked the character of Chaz. Chaz is like Bix from the original series, a proceratops who works as a translator, but his sarcastic sense of humor made him a nice addition among the nicey-niceness of the Dinotopians (although he's never mean or anything.)
If you're looking for a simple adventure/rescue story, if you like Dinosaurs or Dinotopia, or even just good vs. bad (not evil) stories, this is enjoyable and well-written. But don't go looking for gray characters or anyone struggling to accept the Dinotopian way of life... because that never happens.
