I really ended up enjoying this read. The riddle/"mystery" part I figured out almost immediately but I was swept up by the portrayal of the relationships in this book. It was all so human and so raw. Really sheds light on the importance of communication and the importance of knowing when to look outside one's own experience and remind ourselves everyone else is also living out the pains and pleasures of existence. A good reminder to be compassionate, both with yourself and others.
