When I try to classify stories into SciFi or Fantasy I start by thinking, “Is there magic?” To me that’s the dividing line between the two genres. But sometimes things aren’t so clear cut.
My library lists Nalini Singh’s books as sci-fi. I’m not so sure about that. There is a lot of future science and psychic powers but there are also shapeshifters. Magic is never mentioned but shapeshifters seem pretty magical to me.
Ilona Andrews’ series that starts with Clean Sweep has people traveling to different planets and interacting with lots of alien races but there is also a lot of magic in the form of sentient houses.
What other books do you recommend that blur the lines between genres?
