Uldir, Anakin's classmate at the Jedi academy, wants to be a Jedi more than anything.  But he can't even lift a feather with the Force.  He thinks he knows how he can learn faster:  the Holocron.
The Holocron is a cube that holds all the secrets of the ancient Jedi Masters.  By "borrowing" it, along with Obi-Wan Kenobi's lightsaber, Uldir believes he will become a powerful Jedi Knight!
Now Anakin--along with Tahiri, R2-D2, Tionne, and the Jedi Master Ikrit--must race across the galaxy to find Uldir.  If they don't, Uldir could be killed.  And Kenobi's blade and the Holocron will fall into the hands of a very evil man...
