The Barney for best inter-species sex goes to…
Babylon Steel by Gaie Sebold
This is a riot of sci-fi/fantasy fusion, with portals, gods and demi-gods, fey folk, were-beasts, lizardy things, caterpillary things, you name it. Saddest were the fades, who didn’t quite make it through a portal. And there’s sex. Lots of sex, everyone having sex with everyone else, furred, scaled or feathered, male, female or hermaphrodite. So if you think mildly graphic lizard/human sex would turn your stomach, this is not the book for you. Beneath the inventive surface is an excellent multi-layered story with a feisty female protagonist, and a nicely humorous writing style.
