Siddhartha was one of my first great..
..readingexperiences, after that I read Steppenwolf, Under the wheel (Unterm Rad), Morgenlandfahrt and The glass bead game (I don´t know the english titles). When I had finished one I emediately started another. I love german litterature, Hesse & Mann in particular, it´s so (I don´t know if it´s the right word but) perfect. I recomend everyone to read Hesse because he is not difficult to read.
