How have I never heard of this book?

The other week on the subway going home, a woman across from me was reading this book:

I leaned across and was like, "Hey, what's that book you're reading?", and she told me all about it, and it turns out it's all in their: "Smile", how much Mike Love is an asshole, his encouters with the Manson Family, you name it.

The (white) (blonde) woman was very nice, and she said a friend of hers had given the book to her.

When she got up to leave 2 stops before mine, she said good night, and only then did I noticed that she was rather large, with a belly and a big old apple bottom crammed into her jeans.
