Brightstar

Growing up in a military family, Jason and Nicky are closer than most brothers-they are best friends. When Nicky dies in a freak accident, Jason is devastated. He ultimately joins a technology company that has developed a radio-based communication technology that, when deployed, will become one of the most powerful allies to freedom and one of the greatest threats to totalitarianism the world has ever seen. It's called Brightstar.

Regime change is underway in Russia, and the challenger sees Brightstar as the lever he needs to defeat Putin. It becomes Jason's job to deploy it-in the face of an incumbent regime that will deny its installation at all costs. The book ends with a shattering, unexpected conclusion that will stop readers in their tracks and make them beg for a sequel.
