When I read the prompts for A Month of Faves, I keep thinking I have nothing to add. I really thought that about today's theme. But then...
I remembered that I read Falling in Love with Hominids by Nalo Hopkinson. Science fiction is not my genre, which is strange since I love reading horror, and sci-fi and horror often intersect along their borders. I always feel out to sea while reading sci-fi. I do tend to go for speculative fiction. Perhaps it's because the world is only slightly off in speculative fiction, not completely created from scratch.
Falling in Love With Hominds is a mix of all three, a little speculative, sci-fi, and horror. The book is a collection of short stories. Sometimes I couldn't follow what was happening, but when a story hit with me, it really hit.
Along those lines is In Other Worlds by Margaret Atwood. It isn't a sci-fi novel, but a collection of essays and thoughts about the genre. She's a big fan and has a lot of opinions. It was really interesting and way outside my comfort zone!
