The War Has Begun. The Weapons Haven’t Been Found. And Now, the One Person Sent to Find Them Has Vanished.

October 2003. Six months after the Iraq War began, no weapons of mass destruction have been found. The CIA, desperate to avoid another intelligence blunder, quietly passes the hunt to the one unit that doesn’t officially exist: Penumbra Division.

Jermaine Falls, the division’s newest recruit, is sent in to find what no one else can. But when Falls disappears inside Baghdad’s Red Zone, the mission shifts from locating weapons to finding one of their own.

John Bishop knows he should cut his losses. Falls knew the risks. But Bishop can’t let this one go. With no room for failure, he turns to the only person capable of pulling off an off-the-books rescue under the noses of not just the enemy, but the CIA itself.

Lauren Rampling follows Falls’s trail into the most dangerous territory on earth—a lawless war zone where insurgents, militias, and something much more sinister await. With a team of trusted mercenaries along for the ride, what she uncovers goes far beyond a missing operative—it’s a secret that could send the already volatile conflict spiraling out of control.

Can Rampling survive long enough to bring her people home alive? And with Bishop and his best operative gone rogue, will the unsanctioned assignment be the one that finally destroys Penumbra Division from within?

If you live for the relentless espionage thrillers of Tom Clancy, Robert Ludlum, Daniel Silva, Vince Flynn, and Brad Thor, then strap in for Sam Cogley’s most explosive mission yet—THE TRIANGLE.
