Emmet Doyle is mad enough that he and his avian researcher father have to move from Montana to Florida, but nothing goes right. But then, nothing has ever since his mother passed away. Luckily, the park ranger in charge of where his father will be working, Dr. Geaux, has a son about his age, Calvin, and the two hit it off, especially when a short trip through the swamp puts them in the path of killer alligators. One of these killers has shown up, dead, and is the reason that Emmet's father was brought it. It seems to have some avian DNA, and is no doubt bioengineered. In fact, a mad scientist who goes by the name of Dr. Catalyst has engineered the animals to take out invasive boa constrictors, and he feels he is trying to save the Everglades. So does Mr. Newton, Emmet's science teacher, who is suspicious of everyone, including Emmet's father. When Dr. Doyle is kidnapped and ransomed by the deranged man, Emmet and Calvin use what they know about the swamp to try to find him. Unfortunately, Catalyst gets away, so we can look forward to the sequel, Feeding Frenzy, in October of 2013.
