Zero Margin

A kidnapped boy. A corrupt shadow network. A mission that turns personal. Neagley is about to be pushed to her limits.

Former U.S. Army Master Sergeant Frances Neagley has a simple set of rules: protect the innocent, expose the guilty, leave no one behind. But this time, Neagley is fighting a war that tramples all her principles. When a desperate encrypted call reaches her, Neagley reconnects with Madeline Baker, her former commanding officer, now the wealthy CEO of a public security company, and one of the few people she still respects. Baker's son has been taken by a covert syndicate that defies governments, borders, and death itself.

Neagley assembles a precision strike team and dives into a labyrinth of dark-web auctions, compromised intelligence officials, and off-the-books military tech. But every lead points back to one impossible truth: the mastermind is someone they know. Now the mission is personal. And Neagley knows one thing: some missions you choose. Others choose you.
