Confessions of a Teen Sleuth by Chelsea Cain.
As you know, I read and loved series, including Nancy Drew.
So I had to read COATS.
The premise: Nancy is, and always was, real. That evil roommate of hers, Carolyn Keene, used her life and pedaled it as fiction. This book is Nancy's chance to set the record straight.
When this is good, it is very, very good. It's fun, it's snarky, it's full of in-jokes, and it's not for ten-year-olds. It's written with love of Nancy and the genre. When Tom Swift shows up, there are swifties galore. Cherry Ames is obsessed with nursing and nurses. Unless you are a reader, and lover, of genre series up to the 60s, you won't get the jokes. But if you were a fan, this will have you smiling and laughing.
