"Chocolate Fever" by Robert Kimmel Smith

Getting Chocolate Fever can change your ideas about chocolate and life!

Henry Green is a boy who loves chocolate. He likes it bitter, sweet, dark, light, and daily; for breakfast, lunch, dinner, and snacks; in cakes, candy bars, milk, and every other form you can possibly imagine. Henry probably loves chocolate more than any boy in the history of the world. One day -- it starts like any other day -- Henry finds that strange things are happening to him. First, he makes medical history when he comes down with the only case of Chocolate Fever ever. Then he finds himself caught up in a wild and hilarious chase, climaxed by a very unusual hijacking!
