Am quite enjoying this novel by laline Paull.
I'm not sure if it is fantasy or science fiction, difficult to slot into a category but if you are interested in bees, you'll probably enjoy it. I thought I would get irritated by what I expected to be a ton over-researched content loosely held together with a thin plot but I am not irritated at all. It is a real work of fiction and all the scientific facts about bees are secondary to the story (but at the same time, she obviously does know a lot about bees).
Here's a review in the Guardian and there are plenty more on Amazon and in the other newspapers.
