Operation Vanguard is in chaos.
On a post-apocalyptic world in the Taurus Reach, undercover Starfleet Intelligence agent Cervantes Quinn finds an ancient Shedai conduit. Unfortunately, the Klingons have found it first and sent an army to claim it.
Light-years away on Vulcan, reporter Tim Pennington answers a cryptic call for help and ends up stalking interstellar criminals with an unlikely partner: T’Prynn, the woman who sabotaged his career and is now a fugitive from justice.
Meanwhile, Diego Reyes, former commander of Starbase 47, lives as a prisoner aboard a Klingon starship. But his former enemies aren’t seeking revenge. In fact, the only man who knows why Reyes is still alive is the one who arranged his kidnapping and faked his death — the enigmatic Councillor Gorkon.
All their fates, as well as the futures of three great powers, are linked by one thing: the mysterious Mirdonyae Artifact. And unless Dr. Carol Marcus and Ming Xiong can unlock its secrets in time, it might destroy them all.
"[A]n enjoyable and well-paced read. [Cervantes] Quinn's [arc] is spectacular, carving out for the reader a much deeper perspective on his past."
"There are other surprises to be found between the covers of Precipice, all of them worth your time. Mack's visit to the Taurus Reach definitely satisfies a momentary thirst, but will invoke a new hunger in the hearts of Vanguard fans who want to see more. Here's hoping that the 'more' will be on its way very, very soon!"

—Peter Quentin, Total Sci-Fi
"From the beginning, this series has proven itself to be well written and extremely enjoyable. Each successive novel get, better and betteras the characters and story get deeper and more profound."

"What a fantastic novel!"
