The second book in David P. Forsyth’s Sovereign Spirit Saga is titled “Flotilla of the Dead.” Following the exploits of Scott, Carl, and other survivors of the April 1, 2012, zombie apocalypse, the narrative picks up where “Voyage of the Dead” left off. The Sovereign Spirit’s crew and passengers are still working to find a cure for the virus that ended the world as they knew it, save more survivors, and gather supplies for the expanding Survival Flotilla.
