Recursion

Amazon writes, "At first, it looks like a disease. An epidemic that spreads through no known means, driving its victims mad with memories of a life they never lived. But the force that’s sweeping the world is no pathogen. It’s just the first shock wave, unleashed by a stunning discovery—and what’s in jeopardy is not our minds but the very fabric of time itself.
 
In New York City, Detective Barry Sutton is closing in on the truth—and in a remote laboratory, neuroscientist Helena Smith is unaware that she alone holds the key to this mystery . . . and the tools for fighting back.
 
Together, Barry and Helena will have to confront their enemy—before they, and the world, are trapped in a loop of ever-growing chaos.".
I get so frustrated with different timelines and time travel, so this was very frustrating. The ending was like groundhog day only painful. And the very ending - still doesn't make sense to me. The book explains why my reasons for how they could have stopped everything, but it didn't make sense to me. All in all, I say: SKIP IT unless you like that kind of science fiction.
