The battle to save the galaxy reaches new heights of peril and new depths of darkness. The valiant Jedi Knights and clone troopers defend exotic planets from enemy forces. They wage war underwater, battle across a night-shrouded world and take on the merciless Death Watch. Our heroes are tested like never before as Anakin is haunted by the realities of his past, Ahsoka fights to free her people, and an undercover Obi-Wan braves a deadly bounty hunter tournament.

Anakin Skywalker and the rest of his Jedi team have been overrun by the Separatist surprise attacks led by Riff Tamson while Prince Lee-Char and Ahsoka must evade capture on their own.

C-3PO and R2-D2's bizarre caper continues. Forced to escape a Separatist attack in a Y-wing fighter, the droids visit the world of the Patitites, the odd planet Balnab, and the inside of a pirate warship where they are forced to fight in a gladiatorial arena.
When Anakin is forced to temporarily turn over command of his clone troopers to a new commander, the JediPong Krell, tensions begin to run high as the clones are assigned with a very deadly mission to take the capital of Umbara.
GeneralKrell orders CaptainRex and the clone troopers of the 501st Legion to conquer a heavily fortified Umbaran airbase, and will not accept anything less than victory. It is an almost certain suicide mission, unless the clones can use their ingenuity to defeat their new enemy.
