First of all, anyone interested in sci-fi/fantasy should check out Cheryl Morgan's blog - she's been posting tons of wonderful WITMonth pieces and recommendations, particularly for sci-fi and fantasy writers. Lots to explore there... go check it out!
Next, there's my own
I'm not a huge thriller/mystery fan myself, but there's no denying there's quite a bit of different eligible books here: I've heard quite a few recommendations for Juli Zeh, for example, and have encountered Camilla Läckberg quite a bit as well. Here, I encourage checking out blogs like Reading Matters, which doesn't specialize in either genre fiction or literature in translation, yet covers quite a bit of both. I know I'm missing a lot here (being largely unfamiliar with the field...) - feel free to share your favorites below!
Finally, a quick list: Sun-mi Hwang's fantasy-fable The Hen Who Dreamed She Could Fly, fantasy elements in Yoko Ogawa's Revenge, and Isabel Allende's magical realism - all different forms of "genre", each literary and unique in their own ways.
Those are my quick jots... who have I missed?
