Lords of the Sith

"First, as is apparent from that spectacular cover, the book features Vader and Palpatine. It also features a character who I'm not allowed to name just yet, but who appeared in The Clone Wars animated series. In terms of where it fits in the timeline, Lords of the Sith is set after the Revenge of the Sith film and before the forthcoming Rebels television show."

- Paul S. Kemp
