Not time travel per se (although I like time travel books), sort of parallel lives (ditto), more of something along the lines of *The Midnight Library* and *The Post-Birthday World*, or the movie *Sliding Doors*. How one choice you make at a pivotal moment would make the rest of your life very different, for better or worse. Thank you in advance!
ETA: I did not care fo*r The Nine Lives of Rose Napolitano*, everything ended up>! too same-y!<.
