For some entrepreneurs the generally slower summer months are a great time to learn something new or catch up on the latest business titles. For others, vacation season is all about feeding the brain with some great fiction.

Don't knock devouring a pageturner. Not only do figures like Mark Zuckerberg and President Obama credit fiction with expanding their outlook and exercising their minds, but science even suggests that a great novel can boost empathy, a hallmark of excellent leaders.
