We Are Okay

I like this book. It gets across a lot of feeling. But somehow I don't get it. I get that the big secret is something that hurts Marin. But I don't really get the other effects it has on her. That's fine, I can accept it in a "it's never possible to really understand other people, and everyone's so different, that also goes for fictional characters" way, but it produces a lot of distance for me. I also don't really get why that thing gets connected to insanity, it just... doesn't seem that much out of the ordinary to me somehow.
