OK! It's about how aliens take over the humans and other planets and then put the aliens into the human bodies. The story is about a soul whose name is Wanderer but then gets the nickname as Wanda inside a human body and the humans name is Melanie. Then Melanie is still inside there and she wants to see if some humans are still alive so then the whole book is about them searching for the humans!!! It is much better then what I just described so just read it because it is really good!!!!=)
