Twice-Born Book
Del Rey first announced a Plagueis novel by Luceno for 2008, then quietly cancelled it in 2007 — editor Sue Rostoni reported that Lucasfilm had decided this was not the right time to expose Palpatine's backstory. The book was reinstated and rescheduled for January 2012, timed loosely to the 3-D theatrical reissue of The Phantom Menace.
It debuted on The New York Times bestseller list. The audiobook was narrated by Daniel Davis. The hardcover ran 379 pages, structured in three parts spanning roughly 67 to 32 BBY — decades before The Phantom Menace up to its events.
