Both publications are due to hit before the game appears in the summer. And both obviously follow the same storyline, which explores the period between Episodes III and IV where Darth Vader's the big bad daddy of the galaxy far, far away.
"This action-adventure finds the Jedi order crushed under the hand of Emperor Palpatine and a new order risen, one that seeks to dominate the galaxy using the iron fist of Darth Vader. But Vader cannot control an entire galaxy alone and has selected his own apprentice from among those gifted with Force-sensitive abilities. As the fate of the galaxy hangs in the balance, this new apprentice must choose their own destiny."
The novel's been penned by Sean William (apparently a New York Times-bestselling author who has worked on Star Wars novels before), while the graphic novel's being handled by Haden Blackman, a LucasArts writer who's turned his hand to comics.
