It's designed more for kids, but I found it useful for understanding basic accounting concepts: The Accounting Game: Basic Accounting From the Lemonade Stand.

I also found two of the novels in Clavell's Asian Saga to be quite business-focused: Tai-Pan and Noble House. Not so much for the nuts-and-bolts of business, but just a large business organization being founded and growing over the course of multiple centuries.

Get a Grip by Gino Wickman introduces EOS through a narrative story.

I'm a big fan of The Deadline: A Novel About Project Management by Tom DeMarco.

The Five Dysfunctions of a Team by Patrick Lencioni is another classic.
