The Dark Lord Trilogy

StarWars.com summary
Though they weren't originally released as a trilogy, the novels Labyrinth of Evil, Revenge of the Sith, and Dark Lord form a natural story arc that follows Anakin Skywalker's last days as hero of the galaxy and transformation into Darth Vader, Dark Lord of the Sith. Now the movie adaption by Matt Stover and the two flanking tie-in novels by James Luceno are being combined into a trade paperback format that collects all the action, intrigue and drama of the three books into one. The Dark Lord Trilogy is due out in August from Del Rey Books.
