Maybe you should explain whats going on, for instance I had no Idea they were fighting aliens, maybe describe the alien as a scary, lifeless figure that lay on the floor.
I'm not sure this is correct, perhaps "Isaac heard the stranger talk to someone else, in the same mannor as he had to Isaacs mother." ?
Had would make more sense in my opinion. :) Great book by the way.
