Sometimes weird things happen to people. Just ask Jake. He might tell you about the night he and his friends saw the strange light in the sky. He may even tell you what happened when they realized the light was only a plane... from another planet. Here's where Jake's story gets a little weird. It's where they're told that the human race is under attack, and given the chance to fight back. Now Jake, Rachel, Cassie, Tobias, and Marco have the power to morph into any animal they choose. And they must use that power to outsmart an evil greater than anything the world has ever seen. Written by Monica

The Animorphs try out the disk, but nothing happens. Jake and Marco realize that someone very close to Jake is a Controller. The Controller turns out to be Jake's brother, Tom. Jake wants his brother back, and he'll do anything to do it. They tried morphing out into ferocious animals from the clinic that Cassie's mother works in. Jake acquires a tiger and Rachel acquires a lion. They use it to try and free all of the humans in the Yeerk Pool located under the school. Their attempt ended with no free humans, without Tom, Tobias was gone (probably captured by the Yeerks), and the disk was lost. Written by Monica

The Andalite disk is still lost and the Yeerks wish to barter for it: they will trade the disk for an Andalite. Jake and Marco trick a Controller into capturing an actual animal, and think they've gotten away with the disk clean. Meanwhile, the Sharing moves forward with its plans to harvest more Controllers, and the compromise over the disk turns out to be a trap. Hopefully, the Animorphs will be able to outsmart the Controllers. Written by Monica

Once they find it, they destroy the Yeerk Pool in a room and Jake falls into the pool. The Animorphs do not know that Jake is a Controller when they leave. Written by Monica

However, Vissser Three places a morphing detector inside the tower; Jake and Marco get captured and taken to the Yeerk mother ship via a spacecraft.

My name is Elfangor. I am a prince from the Andalite world. I am dying. My ship has crash-landed on a planet called Earth. This is not the first time my hooves have touched the surface of this vast and beautiful world, but it will be the last. The Yeerks have launched their silent attack on Earth. Yeerks are evil parasites who live in the brains of other species. Now their goal is to enslave every human being on this planet.
