Plot summary
The book starts off with the four human Animorphs helping four parrots in a new mall cafe by telling the customers disgusting things about the cafe's food. After this, Marco's old acquaintance, Erek King, who was watching at the room's back, has some disturbing news about his mother, Eva (Visser One). She has returned to Earth, overseeing a Yeerk bio-weapons program to allow them to venture into deep waters; this is a requirement made by the Yeerk command for the invasion of Leera, a planet covered almost entirely by oceans. The research is conducted in the waters around Royan Island. The Animorphs infiltrate the facility, and discover that the Yeerks are trying to create super-intelligent sharks which can be infested and controlled, because in their natural state, the sharks' brains are not big enough. They decide to acquire hammerhead morphs. Marco accidentally reveals to the other Animorphs his fear of sharks. While scouting the waters off Royan Island, the Animorphs are captured by a computer while morphed as sharks. They have devices installed in them designed to bestow sentience on animals. The Animorphs then try to morph flies, but find they can no longer morph into small creatures because the devices are too large for small creatures' brains. They realize the only way to remove them is to destroy the facility, deciding to attempt to do so. During the ensuing battle, Marco reveals to Rachel and Ax that Visser One's host body is his mother, just as they were about to kill her. Visser Three storms in, angry that Visser One would do these experiments without his knowledge or consent, and they have an argument. Visser Three is about to eat Ax in a snake-like alien morph, but Rachel intervenes and grabs him by his wrist in bear morph, threatening to cut him in half. Because of this, Marco sees an opportunity and morphs into a gorilla, knocking out the Visser.
