In enormous lettering the first page warns: "Do not read beyond this page!" The reason? The book contains a secret so nefarious as to be dangerous even to innocent page-turners daring enough to venture forth. The first few chapters present a tricky little exercise in metafiction in which the story about a secret is revealed as being itself too secret to tell, a ploy sure to tickle more puzzlesome readers. But then the intrusive narrator, who is equal parts snarky and delightful, strikes a deal and deigns to tell the story with fake names in Your Hometown, as long as you agree to "forget everything you read as soon as you read it." Then follows a not terribly shocking story wherein two intrepid kids uncover a mysterious society bent on immortality, which gets them in and out of all manner of trouble.
