Selected for the FBI's elite Hostage Rescue Team, Agent Waller gives up a life he thought he understood to dive headlong into a violent world of trapdoor truths and shifting alliances where the greatest threat may be his own sense of right and wrong.

He is not alone. Sirad Malneaux, a beautiful executive at one of the world's top telecommunications companies, turns out to be more adept at murder than marketing. Her true role as a CIA Nonofficial Cover operative will turn a simple assignment into a secret Waller can never divulge.

Jordan Mitchell, CEO of Borders Atlantic and one of the world's richest men, threatens to trade national security for market share by selling a new encryption technology to the Saudis. His shameless love of money is surpassed by just one other passion, a passion only Jeremy is capable of discovering.

Senator Elizabeth Beechum, chair of the Senate Intelligence Committee and front-running presidential candidate, vows to stop Mitchell at any cost. Unfortunately, even her security clearances and insider status cannot protect her from being charged with an unspeakable crime.

Racing from the FBI's secret training rooms to Arabian deserts, from the halls of Congress to the back rooms of Wall Street, and told with a voice only an insider like Christopher Whitcomb could summon, Black lifts the curtain on a world of secret operations, corporate manipulation, and classified technology. It is a world where everything you thought you knew about justice comes to an end, a world where Agent Waller discovers that sometimes the only way to get out of the darkness is to head even deeper into the shadows.
