Thanks Christina!! I've started it and it's alright so far. I'm pleasantly surprised actually, and am finding myself enjoying the story as it unfolds. I haven't gotten far yet, I'm only on chapter 7, but it's an interesting take on the whole "Post Apocalyptic World" scenario. Also, the way the "souls" take over their hosts reminds me of a YA series I read way back when called "Animorphs". Kind of the same concept with a parasitic alien race enslaving humanity one person at a time, first covertly and then when they felt they had enough power, they began to do so openly.

However, both stories have a different take on them, as in "The Host", the host bodies assimilate with their alien parasite and the two become one being, essentially, but in "Animorphs" they alien parasite can only control the host, with the host still alive and able to perceive the world through their senses, though these senses are controlled completely by the parasitic alien.

Anyways, I'm intrigued now and will continue to read on.
