The Name of This Book is Secret, by Pseudonymous Bosh

As with many of my favorite books, this story, The Name of This Book is Secret, revolves around a circus. Often, people who were thought to be missing had, in fact, ran away to the circus, but in this case, children performers have been going missing from the circus. Friends, Cass and Max-Ernest, stumble upon this old mystery when they discover her Grandfathers' Symphony of Smells, a vast collection of vials of various smells. This, in turn, leads to the discovery of a VERY SECRET notebook, sought after by two leaders of a VERY SECRET organization, Ms. Mauvais and Dr. L.

These two will stop at nothing to retrieve the notebook. They lure the kids to a "spa," which turns into anything but a relaxing experience. The two race to save Benjamin Blake, the latest gifted child that has been snatched to be used as an elixir of youth. They must decode ancient Egyptian riddles and outwit an entire underground organization, with hundreds of years of experience on their eleven years of life.

You can imagine the suspense. Literally, there are areas in the book where the narrator asks the reader to come up with their own addition to the story. This breaks up the story and makes the reader feel that they are not only along for the ride, but behind the wheel.

This is the first installment of the five book series, so there is plenty of mystery solving to be had after the last page is read, or, should I say written by you, the reader.
