Welcome to Paradox

Lars Keller is history. Literally. Sentenced for temporal crimes he has not yet committed and exiled to the past with no technology and no way to get back home, Lars soon finds himself caught in an endless cycle of paradox. Unless he can find a way to restore the timeline, Keller will find himself being expelled from space and time over and over again. The catch? If he's going to restore the timeline, he has to do it from the outside.
