In audiobook two of the Davis Sisters Adventures series, South Carolina sisters Karlie and Katherine Davis are asked to find and eliminate a group of global business leaders who conspire to destabilize the economies of the world's five largest economic countries, including the US. 

Based on the Davis Sisters' success in destroying Al-Qaeda, in audiobook one, Warrior Sisters: Revenge for 911, this latest assignment seems relatively simple. It isn't! Both sisters suffer greatly, both physically and psychologically, at the hands of these evil men. In the end, good once again triumphs over evil, but the cost to Karlie and Katherine Davis prove to be enormous. 

The global case of espionage and economic pandering by some of the world's richest and most influential people takes the Davis sisters across four continents and dozens of countries. Success in Goodbye Mr. Kang is measured more so in survival than end results. From the malaise of high-stakes economic and political power-playing emerges a single, mysterious face of evil: Joseph Bolling. 

As the Davis sisters and their cast of friends within ATUR, a highly classified, highly secretive organization within the US Department of Defense, come of age, listeners get a glimpse of life on the seedy underbelly of global espionage, politics, and economics.
