The Oxygen Syndicate

The air you breathe is a weapon. Evelyn, a fifty-year-old lead "Atmosphere Regulator" for Habitat 7, maintains the delicate balance of life inside the dome. She's competent, meticulous, and entirely unnoticed by the elite above her—exactly how she likes it. But her quiet life is shattered when a high-ranking political rival of the Habitat's CEO drops dead in his sealed penthouse, the death ruled a "natural malfunction" of the oxygen lines. Evelyn knows it's a lie. She is reluctantly forced to partner with Leo, a ruggedly handsome technician from the "Oxygen Syndicate"—a shadowy organization the police believe are air-quality terrorists. Leo is the only one with access to the black-market tech needed to track the invisible killer. They discover the CEO is capable of creating localized, undetectable micro-storms and oxygen deprivation to silence opponents. As they become suspects, Evelyn and Leo go on the run, a high-stakes, man-on-the-run romance unfolding as they race to expose the truth before the killer uses the entire city's atmosphere for their next hit. dystopian sci-fi thriller climate fiction series, later in life romance for women over 50 seasoned, enemies to lovers romantic suspense man on the run , corporate conspiracy technothriller murder mystery, dome city habitat survival science fiction noir, mature female protagonist midlife fiction slow burn, cyberpunk environmental crime underground syndicate
