|Title:||Lemony Snicket, The Unauthorized Autobiography|
This book is probably not worth the effort or money.
It is essentially a cryptic set of chapters that bear some relation to the events in the actual series of children's books. However, it isn't at all clear what this book actually says or means. The author hints at underlying things going on in and around the fictional Snicket family, but nothing holds together.
It's only mildly amusing, and often confusing. The reversible dust jacket is the funniest thing about the book, and while it is amusing, it's not enough to justify the purchase.
However, if you're the kind of person that enjoys incredibly complex puzzles, it is possible that there is data in here that will help to unravel the various goings on in the Snicket books themselves. I haven't had the patience for that - in any forum, not just here - and so didn't find the book useful in that way either.
In short, save time and read only the actual Lemony Snicket series.
