The only book that made me teared would be when
died in the Harry Potter's 6th Series. Pretty amazing how I got entangled into that series when I wrongly assumed it to be too childish initially.
Well for me would be "The Revelation" by Bentley Little. A really creepy story which didn't exactly had the happily ever after ending. And worse still I couldn't put down that book at it was loaded with cliff hangers.
