Zero Sum

When a drug overdose claims the life of someone close to Jonathan Grave, the black-ops veteran decides it’s time for a war on drugs that actually looks like a war—in another action-packed thriller from New York Times bestselling author John Gilstrap.

Jonathan Grave long ago lost faith in the so-called war on drugs, a futile campaign that enables cartels to make billions under the protection of corrupt officials on both sides of the border. But when a 12-year-old dies after consuming fentanyl disguised as candy inside the dormitory at Resurrection House, the school JonathanEdit created for the children of incarcerated parents, he knows it’s time to use his special talents to change the game.

Gathering his Security Solutions team, Jonathan goes into high gear. Nobody and nothing will stop them from ending the flow of poison—not even the president of the United States himself . . .
