I frequently perform printed word mashups — simultaneously reading two or more books. A recent side-by-side is Saving the World at Work by Tim Sanders and Buy-ology by Martin Lindstrom.
Title aside, this is more of a book recommendation for marketing people. Read The Drunkard’s Walk, How Randomness Rules Our Lives by Leonard Mlodinow. A terrific discussion on randomness, chance and probability, this book can help marketers understand how numbers can be used and misused.
