Cynthia Cooper was a true corporate whistleblower. She became famous, not by choice, but because of the WorldCom financial statement fraud valued at $11 billion. She was the Vice President of Internal Audit at WorldCom, a position that was not easily obtained. She almost single-handedly created the internal audit department at WorldCom, and her book Extraordinary Circumstances: The Journey of a Corporate Whistleblower details the struggle to get management to take internal audit seriously.

Things started going wrong at WorldCom very early. The company went on an acquisition spree, and the merging of many small companies, managers, and accounting systems was a disaster waiting to happen. Cynthia says that WorldCom was much better at acquiring companies than integrating them, and that is clear.

From an accounting perspective, it was next to impossible to create a properly controlled system. There were too many small systems being pieced together, and it was easy for numbers and authorizations to get lost in the shuffle. This struggle is well-documented by Cynthia, who no doubt painstakingly researched the various acquisitions in order to give such a complete history.

At times the book seems to get a little off-topic as Cynthia goes through each player's background briefly. Honestly, that information isn't really relevant to the story and, while it was probably intended to make these characters relatable human beings, it really just serves to make the book longer than necessary. It prolongs the process of getting to the real heart of the story.
