With thousands of cold sleep passengers, vital data and technology to deliver, the crew battles a desperate enemy in their own ranks.
Can Abishai and the crew of the Nai'a keep the ship they live on alive? Can Captain Brelling, her officers, and her security personnel discover the identities and purpose of the mysterious saboteurs without starting a panic or a witch hunt among the crew?
