From the back of the book:
It is a time of security and prosperity, now that the traitorous Jedi are gone and the corrupt Republic is no more. The Galactic Empire is at the height of its power, but its brutal oppression is driving more and more beings into active resistance. An alliance of rebels is forming to challenge the Empire – just as a weapon of ultimate power is ready to be unleashed on the galaxy.
