It is quite a revelation to discover that the place you wanted to escape to is the exact same place you escaped from. That the prison wasn’t the place, but the perspective.

I... definitely have a lot of complicted feelings about this one.
The beginning of the book hit me really hard. I'm sadly not a stranger to depression or suicidal ideation, and Nora's experience on that day that almost became the last one was frighteningly relatable. I actually had to put the book aside for a couple of days after getting through that first part, because I was afraid to get triggered into a bad mental state at this rate.
Once the actual story with the library and the endless do-overs started, though, I began to gradually lose my connection to the story. I do understand and admire the overall concept. I've certainly wondered about what-ifs a lot in my own life, spent a lot of time trying to imagine where and who I would be if I just did one thing differently years ago. And the concept of exploring those what-ifs until you find something that re-fuels your will to live is interesting, in theory.
In practice, something in the way it was handled here rubbed me the wrong way. I don't think it's the book's fault; I think it's just a certain difference of... perception? Values? Between me and the author, and that's okay. The book is definitely thoughtful, poignant, and incredibly well-written. Even though with all the skips between lifetimes and possibilities things are bound to get a bit confusing now and then, the author does a great job focusing the spotlight on all the right things. It just wasn't exactly the book for me, I think.
