The Knife of Never Letting Go by Patrick Ness
Prentisstown isn't like other towns. Everyone can hear everyone else's thoughts in an overwhelming, never-ending stream of Noise. Just a month away from the birthday that will make him a man, Todd and his dog, Manchee - whose thoughts Todd can hear too, whether he wants to or not - stumble upon an area of complete silence. They find that in a town where privacy is impossible, something terrible has been hidden - a secret so awful that Todd and Manchee must run for their lives. But how do you escape when your pursuers can hear your every thought?
4 out of 5 stars. Good book, very engaging. I've requested the next book in the series from the library already.
