Readers who enjoyed John Scalzi's first book, Old Man's War, will be equally delighted by his second, also set in the universe of the Colonial Defense Forces (CDF) and their perpetual war with alien races. Though billed as a sequel, The Ghost Brigades does not--strictly speaking--take up where Old Man's War left off--though it is set chronologically after the events of the first book, and there is some overlap in the characters. But the principal viewpoint character, Jared Dirac, is new, and quite different from War's protagonist, John Perry: unlike Perry, an Earthman who chooses to have his consciousness transferred to an artificially generated younger body, Dirac is the product of a seemingly failed experiment in reviving a dead man.
