Firefly - Generations

The third original novel tying into the critically acclaimed and much-missed Firefly series from creator Joss Whedon. Mal wins an old map with ancient written symbols in a card game. River Tam can read it, and says it leads to one of the Arks, legendary ships that brought humans from Earth-that-was to the 'Verse. But the closer they get to the ancient ship, the more agitated River becomes.
