What if you could rewrite the past? Quinn Black is having the worst day ever . . . over and over again. The same car blocking his driveway, the same horrific accident he witnesses, the same cop that keeps preventing him from saving his boss from dying in it, and the same memory of a girl from his past that gets sharper each time. Then he realizes he has the power to travel through time and change the future. With infinite opportunities to alter the past, the possibilities are endless. Could he prevent terrorist attacks? Natural disasters? The deaths of friends? Or even go back in time and say the right thing to the girl who haunts his dreams? Unfortunately, the rules of time travel are more complicated than he imagined, and before long, Quinn is thrust into the greatest race in human history. His actions can either save the world or destroy it. And now the man who could turn back the clock is running out of time.

In the four years since he traveled through time to save the world, Quinn Black has settled happily into life as a new space race billionaire, despite the fact he’s no longer able to travel or loop time. But before long, things start to go horribly wrong. The system he created to save the planet mysteriously begins to malfunction. His team receives a cryptic message, and he’s hurled back into the past once again . . . but with a twist. Now, instead of trying to go back in time, he’s desperate to travel in the other direction and get back to the future. As he joins forces with a young Dr. Green to help him find his way back to 2025, Quinn discovers a sinister plot, one so complex that Quinn may not be able to unravel it. Now Quinn must change the course of history once again. . . or risk erasing his own.

Quinn Black thought his work was finished. After all, in the years since he discovered he could time travel, he saved the human race from disaster and restored hope to the world. At least in the current timeline of the universe. Out in the multiverse, the Earth—and everyone he loves—is in trouble again. Someone sent Quinn's team a video begging for help. But if Dr. Green’s assessment of reality is correct, how will he find his way home if he gets lost in the vast expanse of the cosmos? However, the alternative might be worse. Now Quinn finds himself traveling through spacetime to Egypt to stop whatever trouble is lurking in other realms before it finds its way into his. But what he finds is an enemy more dangerous than anything he imagined. Some entity is annihilating civilizations, and unless Quinn can stop them, his is next.
