What are the internal and external conflicts in The Host by Stephanie Meyer?

I need to know the internal and external conflicts experienced by the protagnist and antagonist in The Host for my author project.

Also, who is the protagnist and antagonist??

well, Wanda (wanderer) is the main character, she is good. And she is helping the few humans left live, her Seeker, i guess could be consideredthe "bad guy" or Kyle but he ends up being nice in the end. Also Melanie's aunt and cousin, aren't bad, but they don't like Wanda. You could say all the 'souls' are bad, but they don't try to be bad, only the humans consider them bad/evil...

I hope that helps!

(sorry about the miss spelled words/names!)
