Romantic, scifi, philosophical comedy needs a home

I wrote a novel "Wrong Turn At Antares" on Amazon. It got an OK Kirkus review and a 5-star review on Readers Favorites. Sloppy editing drew a bunch of bad ratings, but that is now corrected. Now onto marketing at bookbub and I find I cannot locate an audience/market. Fucking around with trial ads adds up.

Is there a market for engaging scifi philosophical comedy, as Kirkus calls it?
