I don’t know what some of these reviews are talking about with Jonas and Amanda not having good “on page connection”. I felt it. This was a great read and I really loved the pacing. Multiple universes is a confusing topic so it stands that the ending isnt exactly definitive or rock solid, but I felt like things did wrap up nicely. The characters felt complex and I enjoyed their personalities and interactions and for the most part most of the scientific stuff doesnt get TOO complicated thankfully otherwise it may have taken me out of the story.
