Seven Steps to the Arbiter aka The Kingslayer

The man: Kit Kellan. His mission: kill the king of the galaxy. But it's not easy to take down the most powerful man in the universe. He'll have to outsmart shadowy spies, deadly saboteurs and women as beautiful as they are dangerous. In the end-if he lives to see the day - he'll make a discovery that will change him, and the galaxy, forever.
