Star Wars: Darth Vader and the Cry of Shadows

After he is left for dead during the Clone Wars, a single trooper comes to hate the Jedi who abandoned him. Years later, he hears of a great and powerful warrior--the hand of the new Galactic Empire, Darth Vader! Seeking to serve the Dark Lord, this man, Hock, becomes a stormtrooper and works to gain the respect of Vader. During a mission against a group of remnant Separatists, Hock finds himself fighting side by side with Darth Vader, and the bitterness that had grown inside him is brought to rest.
