Deep sleep
(Book)

Counter surveillance 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 long-time 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.
