I found this book entertaining even though the ending was predictable. It was obvious to me that the journey of undoing some decisions “regrets” ultimately showed her she made correct choices for herself. Many of the “big life” decisions she felt guilt or regret for, were right for her. And that ultimately through this journey should would learn her life was one worth living and go back to the “root life”. But I think the concept of multiple lives at once was interesting vs possible different lives. I often think about how different my life would be had I done this or that, not out of regret but just general pondering on how life is full of variables that lead to different outcomes.
