The Republic is decaying, even under the leadership of Supreme Chancellor Palpatine, who was elected to save the galaxy from collapsing under the forces of discontent. On the tiny but strategic planet of Ansion, a powerful faction is on the verge of joining the growing secessionist movement. The urban dwellers wish to expand into the prairies outside their cities–the ancestral territory of the fierce, independent Ansion nomads. If their demands are not met, they will secede–an act that could jump-start a chain reaction of withdrawal and rebellion by other worlds of the Republic.

The war that erupted in Star Wars: Episode II Attack of the Clones is nearing its boiling point. The Separatist forces continue their assault on the Republic as the diabolical triumvirate of Count Dooku, General Grievous, and their Master, Darth Sidious, fine-tune their strategy for conquest. Capturing Trade Federation Viceroy and Separatist Councilmember Nute Gunray is the mission that brings Jedi Knights Obi-Wan Kenobi and Anakin Skywalker, with a squad of clones in tow, to Neimoidia.

The jungle planet of Haruun Kal, homeworld of the legendary Jedi Master Mace Windu, has become a battleground in the increasing hostilities between the Republic and the renegade Separatist movement. The Jedi Council has sent Depa Billaba - Mace’s former Padawan and fellow Council member - to Haruun Kal to train the local tribesmen as a guerrilla resistance force. But now the Separatists have pulled back, and Depa has not returned. 

After years of waiting in the shadows, Darth Sidious is taking the first step in his master plan to bring the Republic to its knees. Key to his scheme are the Neimoidians of the Trade Federation. Then one of his Neimoidian contacts disappears, and Sidious does not need his Force-honed instincts to suspect betrayal. He orders his apprentice, Darth Maul, to hunt the traitor down. 

The Separatist Alliance, with ruthlessness and treachery, is beating the Republic to every strategic target. But after a costly clash with General Grievous for the planet Kothlis, Anakin has a mission that will focus his anxious mind. Alongside Obi-Wan Kenobi, he is posing as a long-lost native of Lanteeb, an impoverished world on the Outer Rim. This seemingly unimportant planet has drawn the interest of the Seps and Anakin, and Obi-Wan soon discover the disturbing reason.
