I feel like this is a book that is meant for children but can easily be enjoyed by YA/Adults as well, hence the cross-posting.
The Mysterious Disappearance of Leon (I Mean Noel)
written by Ellen Raskin
The Mysterious Disappearance of Leon (I Mean Noel) is an amazing book that can be equally enjoyed by adults and children alike. Adults reading the book see more layers to it than the kids, but the read is just as mysterious and enjoyable (although the idea of marriage at that young an age will be a squicky one). If you have read Ellen Raskin's Westing Game, and even if you haven't, this is a book you really need to get your hands on. I've read some of her other books, but absolutely nothing compares to these two classics. This one comes fully equipped with hysterical characters and plenty of footnotes. It's adorably quirky without trying too hard. Every thing, every hilarious incident, is narrated casually and in a way that just makes it all funnier. Everything is so tantalizingly cryptic, and at times, downright confusing, but it's a huge relief when everything really falls into place and you realize that every event that was narrated is somehow connected to the big picture scheme. Other than all that, it's a very readable book. The chapters are divided up into small sections and just style-wise, it's an easy but really worthwhile read. It really emphasizes the reason why we love Ellen Raskin so much--plot twists and surprises everywhere! The other really nice thing is that the mystery is not at all obvious. Nobody would ever suspect the outcome, but it's such a compelling one! It's got snark, puzzles, humor, definitely not just a kids' book. It is also really nice, at the end, to get closure from all of the characters, so I do appreciate it when authors like Raskin do things like that.
