Karen Traviss is a British science fiction author and the writer of the Kilo-Five Trilogy.
Originally from the Portsmouth area, she currently lives in Wiltshire, England in the United Kingdom. She is a graduate of the Clarion Workshop for science fiction authors, and has previously worked as a journalist and a defense correspondent and served in the Territorial Army and the Royal Naval Auxiliary Service.
In addition to creating her own science fiction universe in the novel City of Pearl and its sequels, Traviss has authored multiple novels using existing intellectual property, most notably in the Star Wars universe. She has also written five novels set in the Gears of War universe, and served as the lead writer for the video game Gears of War 3.
As a fan of the machinima webseries Red vs Blue, Karen Traviss made several references to the series in her Kilo-Five Trilogy. The most prominent is the pronunciation of "Phillips" by the Sangheili as "Phyllis", which reference to two AIs in the machinima: F.I.L.S.S. and Sheila, whose original name was Phyllis.
