Entitled "I Am What I Am," the new book is due in stores Oct. 1 from Michael O'Mara Books, according to Barrowman's official website. According to the publisher, "I Am What I Am" will offer a "more in-depth exploration of John the man . . . his thoughts, opinions and experiences, and in particular [will] focus on achievements over the past couple of years."

Kate Gribble, commissioning editor said in a statement, "I'm absolutely thrilled to be working with John and Carole Barrowman again on a second autobiographical volume. 'I Am What I Am' promises to be just as entertaining, heartfelt and revelatory as 'Anything Goes' — if not more so — and John's many fans can look forward to a very funny, very honest and very intimate treat this Christmas."
