Strange love

Since this is a SF book club, it seems appropriate to add a twist to the topic of "love". We are thus interested in books dealing with unconventional kinds of love -- a "strange love" if you will. You are thus cordially invited to present one or more genre books (science fiction, fantasy, horror, etc) that deal with this topic.

Afterwards we will have a casual and friendly chat about the books, about the subject of strange love, and wherever else the conversation takes us!

You are of course welcome to bring the books you want to discuss, but it's also fine if you don't.
