Billy Corgan is writing a book that he describes as a "spiritual memoir."

Where other musicians may have been satisfied with a straightforward autobiography, the Smashing Pumpkins frontman is approaching his book with typical grandiosity, even down to the title: God Is Everywhere, From Here to There. It will be published in 2012 by St Martin's Press.

Corgan told Rolling Stone he is not even using a ghostwriter. He said: "It's a very interesting take inside my personal life and my band life. I've decided to write this on my own, which is complete insanity. I try to spend an hour a day on the book, which is the time I would usually put towards music writing. So that means I have to find that hour, because I won't give up that music-writing time. It's a journey, for sure."

The singer is no stranger to writing about himself. In 2005 he published a series of lacerating posts detailing the abuse he suffered as a child. But Corgan insists the new book will consist entirely of original material. "When I started talking about child abuse stuff, and people started saying, 'you have no right to talk about that stuff', it was a total turn-off. Because people started saying, 'Well, my Dad ripped my arm off, so you can't talk'. Well, I'm just talking about my journey. I apologise that I didn't get beat more."

Corgan is also working on two new Smashing Pumpkins albums, Oceania and Teargarden, though he is now the band's only original member.
