Miley Cyrus has launched her first book, an autobiography titled “Miles To Go.” The Disney darling set a book signing at Barnes & Noble bookstore in Manhattan, NYC yesterday afternoon (March 5). The book includes Miley’s early years in her native Tennessee and her ups and down during all her 16 years. She pens, “Most of the time you see me smiling – I mean that’s how I got my name! – but that’s not what it’s all about. Everyone goes through hardships and heartbreaks.”
