Prologue
My name is Emma. That's all I can tell you about me, apart from my basic physical characteristics. I'm not telling you my last name, where I live, or any of that. If I do, the Yeerks of this world will find me. It wouldn't matter so much if I was still in my own dimension- because they'd already captured me- but that doesn't matter. I have a second chance now. I'm in a dimension where the Yeerk invasion isn't quite as advanced as it was on my world.
No biological weapons had been unleashed upon Earth. People who were not Controllers still existed. Most of Earth's native plant and animal species still existed. My friends were still alive.
In my dimension, things were completely different. My friends Marco, Tobias, and Cassie, as well as my cousin Rachel and the Andalite, Ax, were all dead.
Yes, you heard me. My *cousin* Rachel. One of the many things about this new dimension I've managed to escape to is that here, I was born as a guy.
Maybe I should explain from the beginning...
