Milton "Cujo" Quattlebaum died on the side of mountain in Mexico. Or so Abel Yeager believed. Then Victor Ruiz gets a call from the State Department. The pilot is alive and incarcerated in a Mexican prison.

This would be good news except for the intervention of a mysterious captain in the Mexican special forces. The captain offers to get their friend released if they undertake a mission on his behalf. If they don't accept, the Cujo will be without protection in a very dangerous environment.

The job? Kill one of the most powerful and feared men in Guatemala: Herman Gustaffson, also known as El Escorpión.

Yeager and Ruiz must risk everything on a deadly trek into a game of deceit, power, and politics. But they are the pawns, and forces beyond their control are moving the pieces.
