Based on my reading of the first
few chapters (which focuses on the main protagonist and setting up the story)
and my email exchange with the author, I'd characterize CASSAFIRE as romantic
SF.
Below you'll find the blurb, non-spoiler tags provided by the author, a brief excerpt, and the book trailer. I
don't normally feature book trailers here, but this one is professionally animated and includes the heroine, which lends it a light SFR flavor. I also think it has an effective, tight focus. (Per Mr. Cavanaugh, the
software used to create the trailer included 3D Studio Max, ZBrush, and
Photoshop.)
At any rate, peruse the information
to discover if CASSAFIRE is up your alley!
