Animorphs: Shattered Reality2000

[first lines]

The Ellimist:
I am an Ellimist. Since the dawn of time, I have observed every detail of the universe. My interests have taken me far and wide, studying beings on worlds throughout the cosmos. Recently, my attention has been drawn to colorful small, blue world known as... Earth. Ruthless aliens called called the Yeerk have begun an invisible invasion, taking control of human minds, turning them into helpless slaves. And now, everything has changed. The Yeerk leader, Visser Three, gained control of a weapon powered by a continuum crystal. But the weapon was more powerful than expected. The crystal exploded and shattered reality itself. Only one thing stands between the Yeerk and ultimate victory: A group of young heroes called... Animorphs.
