Californication

[seal!]

I'm confused, I've searched everywhere trying to find out if Hank Moody is based on a real person but can find no evidence.

Apart from this http://www.amazon.co.uk/God-Hates-All-Hank-Moody/dp/1416598235/ref=sr_1_1?ie=UTF8&s=books&qid=1255420883&sr=1-1

The book that the character in the show wrote is on Amazon.

Now, was this a publicity stunt, or is he actually a real writer?

Cheers
