The Chronology Protection Case
"The Chronology Protection Case" - inspired by Stephen Hawking's "chronology protection conjecture" - was first published in Analog Magazine in September 1995. The novelette was a finalist for the Nebula and Sturgeon Awards, reprinted five times - including in the currently best-selling Mammoth Book of Time Travel - and made into an Edgar nominated radio play by Mark Shanahan. The novelette is cited in Paul J. Nahin's A Writer's Guide to the Real Science of Plausible Time Travel as the only recent treatment in science fiction of Hawking's conjecture, and has been on the syllabus of a writing class at the College of DuPage in Illinois.
The novelette was also made into a short movie by Jay Kensinger in 2002. It was recut, with a new extended ending by Levinson and Kensinger, in 2013, and is currently available on iTunes and Amazon Instant Video.
Phil D'Amato, the lead character in "The Chronology Protection Case," appears in two other novelettes, and three other novels: The Silk Code, The Consciousness Plague, and The Pixel Eye. The Silk Code won the Locus Award for Best First Science Novel 1999; a small excerpt is available on Wattpad. More details on Phil D'Amato at http://en.wikipedia.org/wiki/Phil_D'Amato
