Remember Animorphs? The book series (and, unfortunately, TV series) about children who befriend an alien and morph into animals. If you didn't read the series, you definitely remember the terror you felt in your heart when you hurried past the books covers in the YA section. We thought it'd be fun to compile the most upsetting Animorph covers, just for you. If you can get to the end of this list, you are very brave and deserve an award.
