Yes that was the demographic, but I'm saying it's a bit hardcore for a teen book. The demographic for stuff like that is a little higher than what Animorphs was going for, right?
It's like sure, Land Before Time and Secret of NIMH were meant for kids, but they were still prety dark.
Those movies were by Don Bluth, and I think he said somewhere that you can show a kid things that are quite dark, and it's okay as long as it has a happy ending. Apparently it works. Animorphs didn't go with the don Bluth ideology, since it had a downer ending. Not that I think KAA was inspired by Donb Bluth movies.
