The Name of This Book is Secret

I would have to suggest one of my personal favorite series of books, The Secret Series.  I love reading mystery books, and this series is just about as mysterious as you can get.  The name of the first book is The Name of This Book is Secret, I'm not kidding.  The author, Pseudonymous Bosch, keeps his characters names a secret, for fear that the bad guys, The Midnight Sun, come after him or the main characters (their cover names being Cass and Max-Ernest). It's really a funny book with how Bosch tells it, giving small hints here and there about himself and how everything is a secret and an adventure about finding a big secret.  There are five books total (so far) and each of them have one of the five senses connected to it, this first book being about smell, with something called the Symphony of Smells.  I don't want to give away too much about the book though, you'll have to find that out for yourself.
