What if your future lies in your past?

When Darren Ault meets his friend Lee McCaskill for dinner, he doesn't expect the second course to be a gunshot to the head. Even more unexpected is the fact that the bullet doesn't kill him—instead, it causes the rest of humanity to vanish. Darren's attempted murder has caused a temporal paradox extending back over a thousand years, and now it's up to him to repair the damage.

Embarking on a mind-bending journey through time, Darren encounters Vikings, a depressed Norwegian silversmith, a cult that believes in salvation through pain, a beautiful Hebridean lass, and Archibald Fischer—the foul-mouthed, Kurt Cobain-worshiping Head Librarian of the Library of Timelines, where all of the possibilities that could ever happen are catalogued, tracked, and managed.
