The Defenders of the Dead live in the past while they destroy the future.  They face a revolt of the Young--a band of rebels led by two teenagers, Cerasi and Nield.
Thirteen-year-old Obi-Wan Kenobi and his Jedi Master Qui-Gon Jinn are not supposed to take sides in any war.  But once Obi-Wan meets Cerasi adn Nield, he feels he must join their fight . . .  even though Qui-Gon forbids it.
The rebellion has become personal.
And Obi-Wan and Qui-Gon are on opposing sides.
