Scalzi serialized a chapter a day in December 2002. Tor Books executive editor Patrick Nielsen Hayden offered to buy the novel, and it was published by Tor in January 2005. In 2006, Scalzi won a nomination for the Hugo Award for Best Novel for Old Man's War. The Ghost Brigades was released in 2006. While a direct sequel to Old Man's War, it focuses not on John Perry, the protagonist of Old Man's War, but on the special forces units. The Ghost Brigades television rights was purchased by Syfy in 2014. 2006 also saw the release of The Android's Dream. A satire, it was well received by Publishers Weekly, which called it an "effervescent but intelligent romp"; it was criticized by Dave Itzkoff of The New York Times, who said it was "merely sarcastic when it should be satirical." In August 2006, Scalzi was awarded the John W. Campbell Award for Best New Writer for best new science fiction writer of 2005. In February 2007, a novelette set in the Old Man's War universe, called "The Sagan Diary", was published as a hardcover by Subterranean Press. Scalzi has commented that he originally wrote the book as free verse poetry, then converted it into prose format. An audio reading of "The Sagan Diary" was offered through Scalzi's website in February 2007, featuring the voices of fellow science fiction authors Elizabeth Bear, Mary Robinette Kowal, Ellen Kushner, Cherie Priest, Karen Meisner and Helen Smith. In November of the same year, Subterranean Press also made "The Sagan Diary" text freely available online. In April 2008 Audible Frontiers produced an audiobook of the novelette, read by Stephanie Wolfe. The third novel set in the same universe, The Last Colony, was released in April 2007. It was nominated for the 2008 Hugo Award for Best Novel. Zoe's Tale, the fourth Old Man's War novel, presenting a different view of the events covered in The Last Colony, was published in August 2008. Zoe's Tale was nominated for the Hugo Award for Best Novel in 2009. Also in 2008, Audible.com released the audiobook anthology METAtropolis, edited by Scalzi and featuring short fiction in a shared world created by Scalzi, Elizabeth Bear, Tobias Buckell, Jay Lake, and Karl Schroeder. METAtropolis was planned from the beginning to be released as an audio anthology prior to any print edition. The audiobook featured the voices of Battlestar Galactica actors Michael Hogan,
