When an orbiting launch platform mysteriously explodes and sends a deadly cloud of debris into a U.S. Coast Guard Lifesaving Station, Agent Alex Frost is thrust into the middle of a puzzle. Why had the crew disobeyed orders to abandon ship as the cloud of debris approached? Where was the crew now, as they had seemingly disappeared after the incident? As Frost goes from the orbital crime scene to crisscrossing the globe in search of clues, more questions arise. Why had NASA tried to stop the deployment of the planetary space probes that were destroyed in the explosion? Why was the Milan Aerospace Institute being so secretive about the destinations and missions of the probes? It was becoming clear to Frost that there was more than one mystery to be solved.
