Summary: (Taken from wookipedia)
Prior to the Battle of Yuuzhan'tar that occurs in the novel, a series of events and other battles lead up to Supreme Overlord Shimrra's ultimate downfall, such as the Battle of Selvaris, the Battle of Caluula and the Battle of Dac. And as for the characters who hide on the living planet of Zonama Sekot since the events of the previous novel, which is still in transit in hyperspace, they recover Harrar, who was thought dead in his fight with the treacherous Nom Anor. They also realize that Zonama Sekot is actually the seed of the Yuuzhan Vong home planet, the original Yuuzhan'tar. When the Yuuzhan Vong's violent ways came to notice of their home planet, they were stripped of their Force sensitivity so they would never be detected or be able to contact the Force ever again.
