A gentle and sweet book about books and knowledge and secrets and computers (and computers!) and codes and ... bookstores. I really enjoyed it as I read it, but unfortunately it was in fits and starts so I never really engaged with it. And sadly, two days later, I can't remember that much about it other than that it featured books and secrets and computers. Even the characters have not stayed with me, and I'm kind of sad about that.
But still, if you like books and computers and secrets and codes do read it. And maybe you'll be able to take the time to focus on it and make a more lasting impression than I have.
