My 5 piedra recommendations if you are bored:

The bell by Iris Murdoch.

Ja (yes) by Thomas Bernhard.

Contempt by Alberto Moravia.

The Wind-Up Bird Chronicle by Murakami.

Todos os nomems(all the names) by Jose Saramago.

Check the reviews at amazon or any other place you wont regret about these books. Personally I think the last one is the best.

What are the themes of these books?

Just check the brief synopsis at amazon blue it would take me an hour to give one.
