Hhh. I showed someone the main plot to Toll Booth and the first thing they said was "Just like Animorphs!"

A lot of the charaters can shift, but there's no real bad guy. It's just Awn and Sue trying to make it through the world in one piece. There's no objective other than 'don't be seen.'

And in Toll Booth, they're mixed up creatures, they can be in their form as long as they like, and they only have one form. t(I:Vt

Gracious.
