Animorphs -The Android

In this book, Marco, one of the Animorphs, a person who can turn into any animal, meets his old friend Erek.
Marco doesn't really pay attention to him, but when they find out that Erek isn't a human, he figures out he is an Android. The good part is that Erek has super strength but the bad part is that he is programmed not to do any violence.
I liked this book because the Animorphs meet a new friend. I didn't like it because it gave too many details. But, overall, it was an awesome book.
