A recommendation

I just finished reading this book for one of my last classes. A good story, with a business angle. I liked it because everything about Mars and Hershey is different. The notable fact from the book is that the second M in M&Ms stands for Murrie, who was one of the sons of the President of Hershey. Forrest Mars used him to gain access to supply and distribution contacts.
