Dynasty of Evil: Star Wars Legends

Peace is a lie. There is only Passion.
Through Passion I gain Strength.
Through Strength I gain Power.
Through Power I gain Victory.
Through Victory my chains are Broken.
The Force shall free me.

In my opinion the third and last book in the Darth Bane trilogy is the best. It keeps you on the edge of your seat through the whole thing. Brilliantly written and the story is gripping.
