What are we missing out on Chinese literature or books?

One of the very annoying things when we lived in China was: There were so many books in Chinese we couldn't read!! We have been reading quite a number of Chinese books translated into English or German, but I am sure that there would be much more to explore if only I could muster the language good enough to do so. Argh!

So, to further whet our appetite, I am asking all native speakers and those masters of the language that have attained the black belt of Chinese as a Foreign Language: What indeed are the books we should look forward to reading in Chinese after having passed the newbie, elementary, intermediate and possibly even the advanced level? What are the names of their authors, what are their titles (and maybe what are their ISBN to order them at joyo.com or where to find them for free on the internet - ahem)?

Do not shy away from telling us of crime fiction, poetry, chick lit or drama, but do inform us of classical texts of the past and literary gems of the modern age, too!

Thank you!
