I had low expectations for this one, but multiple people I trust liked it and it was short, so I picked it up. Based on the premise I thought it would be overly sappy (or whatever the book equivalent of Oscar bait is), but it was fun and endearing and bittersweet. It's very dialogue heavy with a voiceover type narration - it kind of felt like a 4-part play. I liked the convoluted rules and getting to learn more about the characters in the overlapping stories. It was a sweet, interesting read that I ended up loving.
