Hard Strike. Decker's War, #7

Terrorists working for traitors intent on transforming the Commonwealth into a brutal empire are preparing to spread mayhem across the vulnerable and increasingly unstable Rim Sector.  Their aim: replace sovereign star system governments with satraps under the direct control of Earth, thereby undoing generations of civil peace between humanity's many fractious branches. During an operation to eliminate a radical revolutionary movement on one of the Rim Sector's most important colonies, Major Decker and Commander Talyn stumble across evidence pointing at a threat more significant than any they've encountered so far, evidence suppressed by Black Sword's remaining moles in Naval Intelligence.
With countless lives on the line, Decker and Talyn race against time and enemies ensconced in high places to undo a conspiracy aimed at reshaping an entire sector before irreversible damage propels the Commonwealth down a dark path which can only end in one last, murderous civil war killing billions. This time, they must strike fast, strike hard and strike without orders from Fleet HQ.  But Decker is tired of fighting the same battles over and over again.  He wants this mission to be the last one and is willing to do whatever it takes.  After all, Decker is not only among Naval Intelligence's deadliest operatives, he's also one of the Few.
