Summary 
From the book jacket
Initially charted by Starfleet probes dispatched to survey the Taurus Reach, the planet Cantrel V now plays host to a budding Federation colony as well as a combined civilian/Starfleet exploration team. Ancient ruins of an unknown civilization scattered around the planet have raised the curiosity of archeologists, anthropologists, historians, and other interested members of the Federation scientific community. Together, they are attempting to shed light on the beings who once called this world home.

After a large, unidentified vessel arrives in orbit and launches a seemingly unprovoked orbital bombardment, the USS Endeavour responds to the colony's distress call. As they attempt to render assistance and investigate the mysterious ship, Captain Atish Khatami and her crew begin to unlock the astonishing secrets the planet has harbored for centuries. Does the survival of a newly discovered yet endangered alien race pose a threat not only to Cantrel V but other inhabited worlds throughout the Taurus Reach and beyond?
