LeBron / Jeff Benedict.

LeBron is unquestionably the greatest basketball player of the 21st century. Off the court, LeBron's political activism, outspoken stance on racism and social injustice have helped build a social media presence that includes 117 million followers on Instagram and 51 million followers on Twitter. He is an international brand worth billions of dollars. He doesn't just have huge endorsement deals with some of the biggest corporations in the world; LeBron sits on boards of directors and has an equity stake in the companies he sponsors. To tell this epic story, Benedict has done exhaustive research, digging through thousands of pages of primary source documents, articles, books and hundreds of hours of video footage. He's also conducted hundreds of interviews with the people who were intimately involved with LeBron from the beginning of his life to the present.
