The Commonwealth Saga is a series of science fiction novels by British science fiction writer Peter F. Hamilton. This saga consists of the novels Pandora's Star (2004) and Judas Unchained (2005). Hamilton has also written several books set in the same literary universe. Misspent Youth (2002) takes place 340 years before the events of Pandora's Star. The Void Trilogy, consisting of The Dreaming Void (2008), The Temporal Void (2009), and The Evolutionary Void (2010), takes place 1,200 years after the events of Judas Unchained; several of the main characters from Judas Unchained and Pandora's Star also appear in the Void trilogy.

Two additional novels, set in the time 263 years before (A.B.D.) and five years after (N.W.S.) "The Void Trilogy", were released in 2014 (The Abyss Beyond Dreams) and 2016 (Night Without Stars).

Like Hamilton's earlier The Night's Dawn Trilogy, the Commonwealth Saga is an epic space opera that extends across dozens of worlds and characters.  (from Wikipedia)
