The book that made me fall in love with reading was "City of The Beasts" from Isabel Allende. I picked it up because my dad had left it lying around, and I completely fell in love. Not only with Isabel Allende, but with reading.
And my favorite book is "One Hundred Years Of Solitud". The first time I read it, was pre internet, so I would write down the name of the characters, to keep track of the family tree. It was just so beautiful, and it really opened me up to fantasy.
