I'm Thinking of Ending Things

I don't know what to think, the first part was actually really boring. But then it picked up and my heart racing but I was so confused. There were so many pieces that didn't feel like they were leading to anything. And I didn't understand the ending at all until I read other people's reviews. I think this book went over my head a little and I didn't appreciate it as much as I wish I would have. I know you're supposed to reread it or something? So maybe I'll try that and I'll get it more, but also who has the time?
