Greg Keyes was born John Gregory Keyes in 1963, in Meridian Mississippi to Nancy Joyce Ridout and John Howard Keyes. His mother was an artist, and his father worked in college administration. When he was seven, his family spent a year living in Many Farms Arizona, on the Navajo Reservation, where his father was business manager of the Navajo Community College. Many of the ideas and interests which led Greg to become a writer and informed his work were formed in that very important year. After another year or so in Flagstaff, the family returned to Bailey, Mississippi, where he and his brother Tim finished their public education and moved on to college. Greg received a B.A. in Anthropology from Mississippi State University, and afterwards worked briefly as a contract archaeologist. In 1987 he married Dorothy Lanelle Webb (Nell) and the two moved to Athens, Georgia, where Nell pursued a degree in art while Greg ironed newspapers for a living. During this time, Greg wrote several unpublished manuscripts before writing The Waterborn, his first published novel, followed by a string of original and licensed books over the following decade-and-a-half. Also during this time, Greg earned a Masters in Anthropology from the University of Georgia and completed the coursework and proposal for a Ph.D., which thus far remains A.B.D. Greg moved to Seattle for a few years where Nell earned her M.F.A. from the University of Washington, following which the couple moved to Savannah, Georgia. In 2005 the couple had a son, Archer, and in 2008 a daughter, Nellah. Greg continues to live with his family in Savannah, where he enjoys cooking, fencing, and raising his children.
Interstellar is his twenty-first published novel.
