The novel starts with a flashback eight years before the Battle of Geonosis when Mandalorian soldier Kal Skirata goes to the rainy planet of Kamino to observe the developing army for the Republic . He finds out that they are cloning his friend , Jango Fett , and that the clones have had their age factor doubled . If the clones have lived a year they will have aged two , and when they have lived two years they will have aged four , and so forth . Skirata is disgusted with the Kaminoans ' practice of " reconditioning " — often a term used for terminating — clone children who didn ' t pass quality control standards . Six " prototype " ARC Trooper children , designated " Null " - class , were labeled defective and scheduled for reconditioning because they would not follow any orders given them . However , before the unruly clones can be executed , Skirata intervenes and takes it upon himself to raise and train them personally , keeping them separate from the other clones . The plot jumps forward to five days after the Battle of Geonosis . Skirata is on Coruscant and has just heard about the conflict and of Jango Fett ' s death at the hand of Jedi Master Mace Windu . The storyline then skips ahead a year later , where the Galactic Republic learns that Separatist terrorists have infiltrated Coruscant and are spying on the Republic . Skirata is hired by the Republic to track them down and enlists Omega Squad — Darman , Niner , and Fi , all personally trained and formally adopted by Skirata , and Atin who was trained by Walon Vau — for the mission . Assisting the team is Republic information broker Besany Wennen , Jedi Master Arligan Zey , and Jedi Knights Bardan Jusik and Etain Tur - Mukan — the Jedi who worked with Omega Squad during the mission to Qiilura . Skirata ' s Wookiee companion Enacca also joins the group , as does Null ARC trooper Ordo and clone trooper Corr . However , the situation is made more complicated when Vau and Delta Squad — Boss , Sev , Scorch , and Fixer — also join the team . Skirata and Vau have a rivalry due to their different philosophies in training clone soldiers . Skirata trained Omega Squad as a role model father - figure , while Vau trained Delta Squad through abusive discipline . Atin has a hard history with Vau since he was beaten so many times under his tutelage . During the course of the story , Etain and Darman ' s relationship grows stronger , and Etain becomes pregnant with Darman ' s child but does not tell him . During the mission to track the terrorists down , Jinart and Valaqil join in to remind Omega Squad and Etain that they still owe the Gurlanin s a debt after they helped the clones and Jedi back on Qiilura . Etain and Omega Squad promise that they will eventually repay that obligation , but ask the Gurlanins to assist in the mission , to which they agree . The spies in the Republic are ultimately found , and the information they captured is destroyed and the terrorists are killed . Unfortunately , the rivalry between Omega and Delta Squads remain ; Atin and Vau engage in a brutal fistfight that is quickly broken up by Bardan Jusik . Later , after the celebration of the squads ' victory over their mission , Etain reveals to Skirata that she is pregnant with Darman ' s child . Skirata is angered by this because he believes Etain used Darman . Nevertheless , the two agree to keep this a secret from everyone else — aside from Jinart and Valaqil — and that the child will be a Mandalorian like his father and not a Jedi like his mother . Skirata promises Etain that she will be able to go to Qiilura and spend some time with Darman . Ordo figures out Etain is pregnant but decides to keep it a secret . Behind the scenes .
