Unlike almost other books recommended in this thread, this jumps straight to the point without a lot of text. From the very start it makes a point and continue without delving into too much intro or background or other plain (useless) text. I find Effective Java an easy read for the exact same reason, it makes a point from the very start without telling so many stories.
