Former clandestine operative Carmen Foxdale is on the mend after being rescued from a dank subterranean Alcatraz Island hellhole. Weeks of brutal torture while being held captive by Latvian mobsters had taken their toll on both her body and mind. After her rescue, she seeks answers as to why she was subject to a kill order and had been disavowed by the CIA. Left with nothing to lose and at the mercy of an ex-special forces operative-who has been tasked with keeping her alive and out of trouble-Foxdale puts her rage to work and begins plotting her revenge.
Desperate for answers as to why she was cast aside by the CIA-which she had loyally served until now-leads her to uncovering a tangled web of deep state plots and shocking conspiracies that would rattle even the most hardened operative.
Vowing to expose the corruption, Foxdale calls upon old connections to infiltrate corrupt agents' operations, determined to bring down the entire house of cards from within.
Seeking justice and truth sets Foxdale and her crew on a collision course, with dangerous foes tugging at the fragile strings of power. Devastating consequences challenge their sense of reality and bring them to unexpected new horizons in the fourth installment of the Sultry Chicago romantic suspense series, "The Abyss."
