Which is your favorite Science Fiction series? Part IV

Which series of Science Fiction books do like the best? This is part four of the polls to find the most favored series. We are looking at a series of at least two or three books. There are many series out there and I could only list a few. I must admit that I have not read all of these. Especially non-English writers’ series. If you have others, not listed please put them in comments. I will add them to later polls. I will publish the results after the poll closes.
