Yikes, this one was replete with horror.
I think there are two scenes from this book that hit me hard, but it was the description of the animorphs being ants and losing themselves entirely to the hive mind that stuck with me.
The absolute terror and horror everyone who morphed an ant felt, that even relative to getting shot or sliced or anything they've experienced so far, losing themselves was the worst experience of their lives, and how they were almost pulled apart and killed by that enemy ant colony. That scene is crazy!
And then of course,
spoilers
Marco's mom. He miraculously finds out his mom isn't dead only to realize that she is a slave that he cannot go rescue right away. Awful.
The machinations between visser one and three are interesting too, that you know it's not just good guys versus bad guys, everyone has their own motives for their actions.
