NBA star Dennis Rodman is now a children's author. The NBA Hall of Famer has penned a book called 'Dennis The Wild Bull.' Rodman recently reconnected with his father after being separated for 42 years and hopes this book will help him better his relationship with his own children. The book's website says it will "convey good lessons to children based on Dennis' own experiences as a world-class athlete while overcoming obstacles as a child." The book is due out later this year.
