Discussion: What's your favorite book series?

I’m in a bit of a “series” phase with my reading. Over the weekend I finished A Game of Thrones, book one in George Martin’s epic and unfinished Song of Fire and Ice series. I also read Fonda Lee’s Jade Shards, which is a collection of four short backstories set in her Green Bone Saga universe. Up next for me: Louise Penny’s Glass Houses, which is book thirteen in her Gamache series.

I love being wrapped up in a good series — their epic scope and depth of character exploration makes it feel like returning to old friends. Few things are more enjoyable than getting totally lost in fiction that goes beyond a single book.

Your turn: What are your favorite series? New, old, completed, unfinished, and everything in between — let us know!
