The NUMA Files (Book 20)
A freighter carrying top-secret computers disappears in the Western Pacific. While searching for a lost treasure, Kurt Austin and Joe Zavala are redirected to look for the missing vessel. They find themselves in the middle of a cyber-war between rival groups of hackers, both of whom want to control the flow of data around the world. With no allies except a group of pirates who operate under their own crude laws, Kurt and Joe must rescue a colleague held hostage - while keeping the computers out of Russian or Chinese hands and the world's digital information safe from the hackers.
