This is the tenth book in Terry Pratchett's series on the Discworld--a flat world, supported on the back of four massive elephants riding on the back of a planet-sized turtle, anything hilarious can happen here, and eventually does. When the last Keeper of the Door dies, there is no one left to remember, and the idea must be remembered. So, the idea seeks to break back into the Discworld, the idea of Holy Wood.
First the alchemists of Anhk-Morpork discover a way to make moving pictures, and then "Cut-me-own Throat" Dibbler discovers the idea of being a movie mogul, then Victor Tugelbend and Ginger Withal discover the idea of being a star. And so, the dream of Holy Wood begins to awaken...but, could that dream be a nightmare beyond anyone's understanding?
As always, Terry Pratchett is the master of telling a story that is both gripping and hilariously funny. Indeed, while reading this book I woke my charming wife up several times, laughing out loud! The author succeeds in keeping multiple storylines on track and easy to understand, and the book zooms along to its finale, and boy is it a funny one. I loved this book, and highly recommend it to you!
