Second Paradigm — Peter J. Wacks

Stripped of his memories and trapped in the year 2044 Chris Nost must unravel the mystery surrounding his own murder. If he doesn't, history is at risk of unravelling around him. Weaving through history, rogue time agents, history thieves, gods, and the Time Corps are all trying to alter the paradox Chris finds himself wrapped up in, and each of them is making it worse. Will history shatter? Will the human race be saved? Will Chris manage to save his own life 41 years after it was stolen from him?
