It's about time for another time loop
Recursion by Blake Crouch
How do you go back and fix the mistakes of your past without actually traveling back in time? Blake Crouch has an answer for that in his latest book. A scientist discovers a way to project her consciousness into the brain of her younger self through memory mapping. I admit it would be awesome to go back and live my life all over again with the knowledge I gained. This is not as awesome as it sounds in the story, though. One small change leads to another, then another. An exponential escalation of change eventually leads to a global nuclear war. This catastrophe is unacceptable to the main characters who have the ability to do something about it.
Preventing the end of the world turns out to be difficult to accomplish (go figure). Our heroes find themselves in an inescapable time loop where they watch the world burn over and over again. Will they sink into a deep depression and let humanity destroy itself, or will they find a way to break free and give the world a fresh start?
Blake Crouch has a style of storytelling that pulls you in and refuses to let you go. I enjoyed the way he plays off of scientific concepts to create interesting situations for his characters. I also loved that his characters were not perfect. They made a lot of mistakes and had to learn and adapt to overcome the consequences of their actions. It made for a great story that I definitely recommend.
