Deep Sleep
Stopping the most dangerous conspiracy to ever threaten America means believing the unthinkable in an explosive novel by Wall Street Journal bestselling author Steven Konkoly.
Countersurveillance expert Devin Gray is unwittingly thrown headfirst into dangerous new territory after the death of his mother. Helen Gray, a paranoid and disgraced former CIA officer, believed she was on the verge of preventing a national catastrophe—a mission worth dying for. Others, including Devin, believe she was chasing delusions. Until he finds what she left behind.
With the help of longtime friend and former Marine helicopter pilot Marnie Young and a loyal team of covert operatives Helen summoned just before her death, Devin is propelled into a high-stakes chase across the country. What he uncovers, clue by clue, is a conspiracy more widespread and insidious than anyone could have imagined.
Now it’s Devin’s mission to destroy a covert network poised to deliver a fatal blow to the future of the United States. And also to vindicate his mother, by seeing the mission through to its treacherous end.

Steven Konkoly
Before Steven Konkoly ever crafted his first tightly-wound thriller, he was navigating real-world tension aboard naval ships and behind the scenes of military intelligence. His background as a U.S. Naval Academy graduate and intelligence officer didn’t just inform his fiction—it gave it teeth. The kind that bite with precision, pacing, and a steady pulse of dread that lingers long after the mission ends.
Konkoly’s novels, whether they delve into the shadowy corridors of covert government operations or the chilling realism of societal collapse, are rooted in a rare kind of authenticity. His thrillers don’t just move fast—they move smart. Characters operate in murky moral waters, facing decisions where the right answer isn’t always clear, and trust is as dangerous as any weapon. From The Black Flagged series to The Perseid Collapse, his work examines what happens when systems fail and people are forced to navigate the fallout with little more than instinct and grit.
