Recs if you like Skin Deep...

A list of books in the SciFi/Fantasy genre that heavily feature polyamory. Excludes harem romances, but includes other forms of romance.

Cats as side kicks, cats that make symbolic appearances, cat companions, cats lounging prominently, named or unnamed cats just being cats and humans who love them.

These books aren't about cats. They are just in there.

Or short SFF books for the cold and dark months when you need quick stories and can't focus on big tomes.

They all have under 200 pages, but are very different, so you can try new things or find new favourites.
