8 new bangers just beamed up into this list (one’s an alien centipede! one’s an alien bee!)

Here’s what I looked like flying through the galaxy to find these reads alien cat in a space ship

Note: the Meg Smitherman additions (Thrum, Swallowed) are not your typical romance or erotica. More like horror with romantic subplots. But this list wouldn’t be the same without them. 🥹

Note: R. Lee Smith’s books (Cottonwood, The Last Hour of Gann) are dark sci-fi with romance subplots!! Don’t hop into those expecting erotica!

be careful
