This is the third book in a four book series.
Ender’s long search for a planet where the Formic hive queen can settle and rebuild has finally ended. The planet Lusitania is now home to the only two sentient Alien species known to man. The Formic, and the native Pequeninos, known as “The Little Ones”.
Lusitania also has a unique virus called Descolada. Descolada is deeply intertwined with the native life on Lusitania. The Pequeninos cannot even complete their life cycle without it.
But Descolada is deadly to outsiders. Humans and the hive queen alike must fight an ongoing war against the virus just to survive.
Upon hearing of the virus, the Starways Congress is so alarmed that a fleet of warships is dispatched to destroy Lusitania along with all it’s inhabitants. Mankind is on the brink of committing xenocide for the second time.
