I was really skeptical going into this read. I really had no clue what it was about but it was rated high on the sci fi section. Started reading and I almost put it down for good. This didn't seem like my kind of book. Not sci fi enough. Then a couple of weeks later I decided to give it a try again. Got through the major event where she gets to the library.....THEN I finally understood what it was about and I was friggin hooked! I have always thought these kinds of things in my head too. What my life would be like if I had made one small or big different choice earlier in my life?? I'll leave it at....by the end of this book, I knew how it would end but I still couldn't wait to get there and was sad it ended. This could easily be made into a series, a more modern and personal Quantum Leap. One of my favorite books of 2020
