I really like Gilles Deleuze's books. My favorites are Thousand Plateus & What is philosophy ? (2 books written with Felix Guattari) but I really appreciate everything done by him. The books on cinema are really awesome too.
I read it in french (my first language).
There is this really good website La voix de Gilles Deleuze where you can listen to some of his lessons as Professor : http://www.univ-paris8.fr/deleuze/
