I wish I could explain why I loved this so much, but it's probably something deeply personal. Anyway, read it. It's good.

It's dark, but hopeful. I was nearly crying by the end of my second read. I think I've grasped at least part of why I like this book. I feel seen.

If you're the sort that expects your future to be bleak, especially if or because you don't have a spouse and / or children, and you're introverted, (and of course, you love reading) and can't imagine someone actually valuing you, I think you'll really like this book.
