3.5 stars rounded to 4. If there is something like creature horror fantasy, this is it. In hindsight, however, it may rather be some kind of science fiction horror, since some of the explanations dropped are of the scientific kind, or try to be. What are the explanations about? Well, judging by the intriguing cover, you'd guess dragons, right? Wrong! The book draws on Native American legends about huge birds, strange flying beasts, and ancient winged monsters. We're thrown right into the story, thankfully without any flashbacks. There's a lot of action, until we reach the point at which we can form some kind of idea about the creature (after a couple of awesome attacks on Chicago and St. Louis). Some interesting characters are introduced, with very adult problems and attitudes, who are tasked to deal with this mysterious situation. The attacks are described in detail, the descriptions are quite graphic, if not gorey, people's reactions are very believable, and the whole treatment of the issue, both politically and in terms of city management, utterly convincing. What threw me a little bit is how the situation is resolved: it felt rushed, too character-driven, and somehow it didn't really fit the large-scale level of the story: a city-destroying beast dealt with by three people hunting it to its lair? I'd say that's 20th century Hollywood, not 21st century horror. But others may appreciate this more than I do. In any case, if you love a good monster story, this is the book for you!
