Legendary Motley Crue bassist Nikki Sixx has announced he is working on two new books, his third and fourth, with the first due for release next summer and the other sometime in 2013.  Sixx did not reveal either book's title or subject matter, but stated on his Facebook page:  "Neither book is like anything I have done before.  I pride myself on not writing the same book over and over and also not using a ghost writer. Of course, it takes longer, but raw honesty through words is what I am driven to publish... After I get it all out on paper, I use a trusted editor to help me carve it into a palatable experience..."  The hard rock icon also did not say whether the books would be acompanied by albums from his band Sixx A.M., as the first two books were.
