Science Fiction Time Travel

Henry Long doesn't have a heart. Since the Tragedies, he doesn't have much: just an annoying low-watt buzz from his makeshift transplant, skinny arms, and a dusty library attic from which he charts the slow progress of reconstruction in the Green Zone, the last habitable neighborhood of his troubled coastal city. While his parents work on making the Green Zone independent from a federal government that appears to have abandoned them, Henry himself feels increasingly left on his own.

This audiobook contains a broad overview of time travel in science fiction, along with a detailed examination of the philosophical implications of time travel. The emphasis of this book is now on the philosophical and on science fiction, rather than on physics, as in the author’s earlier books on the subject. In that spirit there are, for example, no tech notes filled with algebra, integrals, and differential equations, as there are in the first and second editions of Time Machines.

Jon's growing concern with what he sees as a corrupted time line is beginning to look like an obsession. Yeah, those never end well.

Not only that, but they are occurring with ever-increasing frequency and bone-chilling severity. Even Jon's minor tweaks to past events backfire with an intensity that would give pause to a normal person. But not Jon Ryan! The man's relentless.
