Synopsis: From the back cover of the 2019 paperback edition: "The Marines of Ghost Squadron are humanity's foremost black ops specialists who strike without warning and vanish without a trace. They will do whatever is necessary to protect humanity anywhere in the known galaxy. With the Commonwealth increasingly unstable thanks to venal politicians, greedy financiers, and power-hungry revolutionaries, they don't lack for missions. When an undercover Constabulary officer vanishes after uncovering a massive cartel-run human trafficking operation, the Commonwealth's interstellar police force calls for help from Naval Intelligence. Because the cartel's operations could upend the delicate political balance between the older core worlds and the more recently colonized outer star systems, Ghost Squadron gets the job. Its mission: find the missing Constabulary officer and choke off the growing slave trade bedeviling humanity's perilous galactic frontier. Ghost Squadron's commanding officer, Lieutenant Colonel Zachary Thomas Decker, spent the last ten years as a Naval Intelligence agent. His job was thwarting plots and terminating the Commonwealth's internal enemies alongside his partner, a trained assassin. Now, with several hundred of the deadliest Marines ever fielded at his back, Zack Decker will change the course of history and usher in a new era."
