The Invention of Hugo Cabret

"A good heavy book holds you down. It's an anchor that keeps you from getting up and having another gin and tonic."
- Roy Blount, Jr.

I read a book recently that was huge, but very fun and diverting. The Invention of Hugo Cabret by Brian Selznick was the winner of the 2008 Caldecott Medal, which is the award for the year's best American picture book for children. Normally the award is given to a stereotypical book, with big pages and pictures, but this book looks more like a Harry Potter novel.
It's 533 pages, but the fun thing about it is that the story is told with both words and pictures so that when the main character is running through the train station there are pages to illustrate his run. It's great fun.
