MOST CHOCOLATY NOVEL - IT'S NATIONAL CHOCOLATE DAY!
Yep, I've gone for the blindingly obvious choice here. No surprises, it's the fantastic Charlie and the Chocolate Factory by Roald Dahl.
Five children win a competition to visit the magnificent chocolate factory owned by the mysterious Willy Wonka. Four of the five children are pretty unpleasant individuals, with equally unpleasant parents. Charlie is the only one who is a decent person.
Chocolate might be sweet, but there's no sweetness in Willy Wonka as he humiliates the grotesque children and their equally horrible parents, ejecting them from the factory one by one until only Charlie and his grandfather are left. Ignore the film versions of this book, they can't quite capture Dahl's subversiveness and dark undertones.
I loved this book and its sequel, Charlie and the Great Glass Elevator. In fact I loved it so much, I still have my rather tatty Penguin edition from the 1970s. And here it is.
