Deceived: star wars legends (the old republic) (Random House Publishing)

The Sith Empire rises from the ashes, set on a path of destruction and devastation in the wake of one of its most sinister dark lords--Darth Malgus. Our time has come. For three hundred years we prepared; we grew stronger while you rested in your cradle of power, believing your people were safe and protected.

You were trusted to lead the Republic, but you were deceived, as our powers of the dark side have blinded you.... You were deceived and now your Republic shall fall. It is a time of vengeance in a galaxy far, far away.

Darth Malgus steps out of the shadows to lead the Sith in striking a fatal blow to the heart of the Jedi Order. Crimson blades rain death and pain upon the Republic, seizing control of Coruscant. But even in triumph, Darth Malgus discovers betrayal aby his own brethren, a quest for peace with the Republic that will only corrode their hard-won power.

As the dark lord plots against the Sith leading their own kind to ruin, vengeance hunts him in turn. Her name is Aryn Leneer--a Jedi with nothing left to lose on a quest to avenge her slain master.
