What do a just-fired physics professor, a woman who may or may not have jumped to her death from the Golden Gate Bridge, an anti-technology movement, and the strangest time machine you'll ever see have in common? They're all major players in Valkyrie's Flight, a hard sci-fi novel that takes a decidedly different look at time-travel. Professor Sam Collier loses his job and his life's work in one morning. His breakthroughs in the field he created, Temporal Dynamics, were noticed all right -- by all the wrong people. It's 2029, and recent technology related disasters have spawned the NoTechs, a rabidly anti-science political party infesting governments and universities across the nation. When a group of pro-science students contacts Sam and offers to help him fight the NoTechs, he figures he has nothing to lose. His lovely new lady friend seems interested enough in him, but there's something unsettling about her -- could she be a NoTech spy? Without his university lab, Sam can't pursue his time research until a scruffy hobbyist describes a strange new phenomenon he's created with almost-deadly results. Sam realizes the "thing in Keith's workshop" could be the key to viable time travel, but how to achieve the crazy initial conditions for a formal experiment? Can Sam and his group complete and test his time machine before the NoTech goon squad closes in? Whose side is Katherine really on? If you like good, hard science with a bit of a new twist on tripping through time, check out Valkyrie's Flight.
