Commander Robert Sheppard and his crew aboard the Phoenix have a sworn duty to uphold order in the universe. Even when that duty means they have to put their lives on the line, each individual is ready to make the ultimate sacrifice for the Alliance of Worlds. In his latest adventure, Sheppard may have to do just that. He is facing dangerous new enemies with advanced technology, weaponry, and intelligence. It might just be his most deadly adventure yet!

When Sheppard is asked for help by his new allies, the Talcon, he can hardly refuse. From their planet-sized spaceship, the Talcon Starcity, the alien race is looking to establish colonies in the Milky Way. Their impressive technology forces all other planets and organizations to play nicely.

The Talcon have a problem that they think Sheppard can solve. Animals from Starcity are going missing. It seems like such a simple mystery, but the solution to the puzzle will take Sheppard across space and into the hands of a strange new entity. Despite his many years working for the Alliance of Worlds, there is still much Sheppard doesn't know about the universe and its many species. He'll soon discover some hard truths!
