I haven't laughed out loud because of a book...ever. This book is hilarious. It's not a book in the traditional sense, more of a collection of illustrations or modern comic strips. Although technically, this book is based on the wildly popular web comic series and subsequent fears Deep Dark Fears.
The "fears" are based on more creepy, funny and idiosyncratic fears, not like a really unsettling episode of Criminal Minds. Fears like what happens after your mouth is numbed from a trip to the dentist and creepy attic bedrooms.
