Books

If you know me well, you should know that I'm very keen on reading! I try to read something useful each day, but I still have a big room for improvement - I read to slow! Anyways, that was not the topic, just an introduction!
I have noticed recently that I am bying the same kind books, which is absolutely normal, but I want to actually broaden my horizon and here comes the question! As easy as you can imagine - Which books do you like to read? Which pen/pencraft? And what would you recommend me to read?
