Charlie and the Chocolate Factory (Charlie Bucket #1) by Roald Dahl

Charlie Bucket desperately wants to eat more than cabbage soup every day. But, even more than that, he longs to see Wonka's ENORMOUS CHOCOLATE FACTORY!

Now Mr Willy Wonka, the most wondrous inventor in the world, has hidden golden tickets inside his delicious creamy chocolate bars. Only five winners can go through those great iron gates. Will one of them be Charlie?
