Greg Egan (1961- ) publishes works that challenge readers with rigorous, deeply-informed scientific speculation. He unapologetically delves into mathematics, physics, and other disciplines in his prose, putting him in the vanguard of the hard science fiction renaissance of the 1990s. A working physicist and engineer, Karen Burnham is uniquely positioned to provide the first in-depth study of Egan's science-heavy oeuvre. She traces the author's career from his early short stories through novels like Permutation City and Schild's Ladder and the Hugo Award-winning novella "Oceanic," analyzing how Egan used cutting-edge scientific theories as a way to explore ethical questions and the nature of humanity. As Burnham shows, Egan's collected works constitute a bold artistic statement: that narratives of science are equal to those of poetry and drama, and that science holds a place in the human condition as exalted as religion or art. The volume includes a rare interview with the famously press-shy Egan covering his works, themes, intellectual interests, and thought processes.
