The second installment of a two-book Obi-Wan Kenobi and Anakin Skywalker adventure finds them trapped on the Separatist-controlled planet and on the run from General Lok Durd and his droid army. They're under siege, and the little time they've bought themselves is running out.
On the Outer Rim, the planet Lanteeb has no strategic value, no political power, and one enormous problem: It has been invaded by an emboldened Separatist Alliance. To find out why, Jedi Knights Anakin Skywalker and Obi-Wan Kenobi have snuck onto Lanteeb--and now look oblivion in the eye. . . .

Hiding their lightsabers beneath their dusty disguises, Anakin and Obi-Wan draw on their Jedi skills to stay one step ahead of Lok Durd's droid army on Lanteeb. The Jedi know that a captive scientist has given Durd the keys to a terrifying bioweapon. Durd knows that the Jedi are on his planet. With Yoda calling on the powers of the Jedi Council, with a new Separatist technology jamming the Guardians' communications, and with a traitor at the heart of the Republic's government, the wheels of war are turning. But the Separatists have blockaded Lanteeb. The finishing touches are being put on a weapon to destroy whole worlds. And it will be up to the two Jedi Knights and their most trusted comrades to liberate Lanteeb or forever suffer the consequences.
