Torch Song by Shelley Singer (
ISFDB,
SYKM), 1st in her Blackjack trilogy of post-apocalyptic dystopian sci-fi action adventure thrillers starring an apparently lesbian mercenary (apparently also YA, from the categories which include LGBT and lesbian, though that may refer to a relatively minor character instead of the lead), originally out from Five Star in 2007 titled as "Blackjack", under the pseudonym of Lee Singer.
IT’S 2066. AND YOU CAN'T TRUST ANYBODY…
Rica Marin’s a mercenary—a hired gun, soldier, and spy who answers only to whoever can keep her in the meds she and her only living relative need to survive the plagues that scourge the earth after biological warfare’s wiped out pretty much everything.
It’s a strange world that’s left—composed of tiny city-states like Redwood, Sierra, and Rocky—run with a variety of futuristic machines and broken-down ones. Fancy new cars float as well as roll, but the Internet’s now so glitchy you can't even blog properly—newspapers have come back! So many machines are in disrepair that a fixer in this world isn't someone who rigs elections or cleans up after murders—it’s a person who can repair both an elevator and an ancient toilet. But roving bands of bandits, godders, causies, breeders, khakis, and toxies threaten to destroy what’s just been fixed.
Anywhere there are people—however few—there’ll be power plays, and Rica’s current job at the Blackjack Casino is to run interference between the warring clans of Tahoe, in tiny Sierra. But then the city-state of Rocky gets ambitious. And that means war.
