Fahrenheit 451 by Ray Bradbury

This is a short work of fiction that speaks volumes.  Montag, a fireman, starts to feel he is not doing the right thing, that there is more to life.  This book follows his change, how it affects him and others.  The parallels I came across relating to today and society were quite eye opening.  Get out there, read a book and experience your environment, you never know when that 'freedom' may be taken away.
