Nearly two years after he almost died from an overdose in a Nevada brothel, Lamar Odom tells In Touch exclusively he is staging a comeback on his own terms, by writing a tell-all book.

“I have a book coming out, an autobiography about my life,” he revealed at the Nickelodeon Kids’ Choice Sports awards on July 13. “[The book will cover] everything. Everything. It’s a free-for-all. [I’ll be] open about everything that’s been going on in my life, about the past.”
