I listened to this as an Audible. I loved it. It was a bit slow, but not so much that it became boring. The amazing ending made it all worth it. Rarely do you find a book with an ending you do not see coming! It helped that I didn't really know what this was about, I hadn't read any spoilers or synopsis. I would suggest you do the same! All you need to know going in is this is the story in two people's POV: a psychiatrist and a patient who does not speak but through her journal entries. So very good! I highly recommend this book.
