When Tobias spots it before they get the chance, the Animorphs decide to steal the ship, to show the world that Earth has been invaded.That's when things go terribly wrong. Before they know it, Jake and the other Animorphs find themselves in another place. Another time. And there's no way home...

Jake is just a normal kid. Well, as normal as possible considering he can morph animals, and he's in a war against parasitic aliens. But as unbelievable as it sounds, something even stranger has happened. One morning Jake wakes up, and he's twenty-five years old.Okay. Maybe it's a nightmare. Or maybe Jake's just lost it for a while and misplaced a few years. And there's another problem. The world Jake-the-kid went to sleep in has changed. It's ruled by the Yeerks. Jake has to find out if the other Animorphs are still around. Still somehow fighting. Or if he's really on his own...

Tobias has gotten used to his new life. He's a red-tailed hawk with the mind of a kid. It was difficult when he first became trapped in his morph, but he's started to come to terms with things. After all, how many kids actually get the chance to fly?But now Tobias is about to make a very difficult choice: a choice that the other Animorphs know nothing about. And it could mean the difference between living the rest of his life as a hawk...and being human.

No more Animorphs. No more planet Earth.
