Product description

From the Publisher

Steven Konkoly is an expert at action-packed thrillers. An exhilarating character that rivals Tom Clancy’s Jack Ryan, Devin Gray is just the highly-skilled action hero I absolutely love. A man whose quick thinking can prevent impending catastrophe. A man who’ll do anything to defend the ones he loves.

Devin Gray is a countersurveillance expert who’s used to the most covert of missions. Not to mention he grew up the son of a CIA officer. Back then, Helen was viewed as delusional. She’d say she was on the verge of uncovering a massive conspiracy, unable to let go of an unsanctioned off-the-books investigation she was determined to prove warranted—an investigation that Devin knows led to her death. Now Devin sees the truth in his late mother’s words...and he’s ready to pick up where she left off. He won’t let her death be in vain.

With pacing that will have you flying through the pages,
Deep Sleep not only delivers an exhilarating read but also an emotional punch—proving just how far we’ll go to protect our family.

—Megha Parekh, Editor

Steven Konkoly is the Wall Street Journal and repeated #1 Amazon bestseller of over twenty thrillers.

Steven graduated from the United States Naval Academy, receiving a bachelor of science in English literature. He served the next eight years on active duty, traveling the world as a naval officer assigned to various Navy and Marine Corps units. His extensive journey spanned the globe, including a two-year tour of duty in Japan—and travel to more than twenty countries throughout Asia and the Middle East.

From enforcing United Nations sanctions against Iraq, as a maritime boarding officer in the Arabian Gulf, to directing aircraft bombing runs and naval gunfire strikes as a Forward Air Controller (FAC) assigned to a specialized Marine Corps unit, Steven's "in-house" experience with a wide range of regular and elite military units brings a unique authenticity to his thrillers.

He still wakes up at "zero dark thirty" to write for most of the day. When "off duty," he spends as much time as possible outdoors or travelling with his family--and dog.

Steven is an active member of the International Thriller Writers (ITW) and Science Fiction and Fantasy Writers of America (SFWA) organizations.
