Which is your favorite Science Fiction series? Part V

Which series of Science Fiction books do like the best? This is part five 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 many 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.
