I can't say what I liked best about this book without writing a bunch of spoilers, but here's what I can say:
It's in first-person, but is a really great example of how to write in first-person well.
I ended up caring about all of the protagonists a lot, to the point where I miss them now that I've finished reading.
I didn't like the little tarot readings at the beginnings of chapters because I have exactly zero experience with tarot, but it didn't ruin my experience or anything. I probably would have enjoyed it more if I did know about tarot, though.
Literature Basically the best book I've read all year.
