At the end of Shadow of the Giant, Julian Delphiki - called "Bean" at the Battle School by Ender's jeesh - fled to the stars with three of his children: the three who shared his engineered genes that gave him both hyperintelligence and a short and cruel physical life. The time dilation granted by the speed of their travel gives Earth's scientists generations to seek a cure, but to no avail.
In time, they are forgotten - a distant voice on the ansible speaking of events long past. But they are about to make a discovery that will change the future of the human race.
"Card's storytelling and world-building are fantastic, and fans of the series will surely be pleased." - School Library Journal
