I LOVE a good duology, especially when it’s sci-fi or fantasy. One book is never enough, but waiting for a series to be completed can be maddening. That’s why I think duologies are the sweet spot. With a series of two, you don’t have to wait too long to find out what happens to the characters, but you get just enough to really sink into them and get to know them. Sure, I appreciate stand alone novels, but for fantasy or sci-fi specifically, there’s so much to the world that I love being able to spend some extra time appreciating all the nuances.
Here are some of my favorite sci-fi and fantasy duologies!
