Both former President Barack Obama and Berkshire Hathaway CEO Warren Buffett have been enthralled by the same book this spring: "The Moment of Lift: How Empowering Women Changes the World," by Melinda Gates, a philanthropist and the co-chair of the Bill & Melinda Gates Foundation.

"I read it one sitting, it captivated me so much," Buffett told CNBC's Becky Quick during an interview on "Squawk Box" on Monday. "It's a story, but [you also] learn much about the world that you should know — and I would say most people don't know. This is a story of her experiences that is absolutely sensational."
