(view spoiler)[ I was confused as well about that. I also thought maybe it was meant to be a bit cyclical timeline wise to the beginning of the book as it ends at 6:30AM and the book started with 6:30AM, but I realize that could also just be the looping of the full 24 hours. When she thought she wanted Peter to come to "end this," I took it as a sign that she was going to keep looping around between Jonas and him all summer and maybe the rest of her life. As other reviewers have said, she will see Jonas the rest of the summer at least so how will it resolve itself?
Part of me wants her to end up with Jonas but Real Life dictates she probably will stay with Peter. (hide spoiler)]
