Here's a signal boost for a post at The Mary Sue called 10 Sci-Fi Stories Created by Women of Color. Most of the featured books are SF, but it includes Alyssa Cole's post-apocalyptic romance RADIO SILENCE (Carina Press)! (hat tip to author P.J. Dean for the heads up).
And at Spacefreighters Lounge, Author Pippa Jay shared a list of books she read and reviewed the past few months and many are science fiction romances! Perhaps you'll find a few discoveries of your own among her selection.
