The Myriad: Tour of the Merrimack #1

The forces of Earth and their long-time enemies, the Palatine Empire, are forced into an uneasy and fragile alliance to stop the Hive, an alien life-form that is devouring its way across the galaxy, and Captain Farragut and the crew of the Merrimack find themselves on the front lines when they stumble upon three mysterious colonized worlds that have escaped the Hive.
