- Tendency towards run-on sentences. Try and be a little more concise.
- Is this story fairly heavy on the sex? Because that's the impression the blurb gives. If it is, no problem, but if it's not, or you don't want to emphasize it, consider changing that.
- "The sport of bio-augmented female wrestling turned women into 8 foot tall beauties who battled in the ring for entertainment, fortune and fame." Clunky, awkward, too long. Rewrite for clarity. Also, more details about the setting here rather than at the end. I don't even know it's 'space'-y until the last few lines.
- "As Size Queen abandons showbiz and uses her augmented body to become a mercenary, She Wolf clings to hopes of stardom by launching a new career in the entertainment industry." Again, real names.
- "Follow their journeys, as Size Queen and She Wolf each struggle to carve out their own unique existence on a future Earth, where sex and starships meet pimps and political unrest, and where supercountries and cybermercs jostle for position in a new global space race." Again, way too long.
- "Follow their journeys" Not bad, exactly, but it doesn't quite fit with the usual conventions of a blurb.
- "as Size Queen and She Wolf" probably don't need to repeat their names here. Redundant.
- "a future Earth" Again, make this clearer earlier on.
- "where sex and starships meet pimps and political unrest" - change this entirely. None of these things contrast with each other, or are even things that wouldn't normally be together, which is what a 'X meets Y' needs to do. Having both 'sex' and 'pimps' in here is again highlighting the somewhat-pornographic vibe this gives. Try and focus on the gladiator/cybernetics aspects, as those are what stand out.
- "and where supercountries and cybermercs jostle for position in a new global space race." Supercountries sounds weird. Cybermercs sounds bad, like a shitty hacker movie that jsut adds 'cyber' onto nouns to make them sound cooler. If there's a legitimate reason for it, keep it, but if it's just to make 'mercenary' sound cooler, then consider changing it.
