I have The Host on loan from a friend, and to tell you the truth, I don't think it's any good.
Granted, I couldn't get through the first chapter, so it might get better. I'm pretty sure it won't. It's not that the story isn't interesting, (it is, despite how very Animorphs it feels), it's just how she writes.
So, I'm still debating on finishing it for the sake of discussing. Let me know if it gets any better?
