dark tower series - possibly a spoiler here...

[mandimoo]

i am mid way through Song of Susannah, the last but one book of the series. King is just introducing the idea that the Gunslinger and his crew are actually characters from a book by none other than himself. I am sooooo disappointed, what a cop out. He has used this idea at least twice before in other books. is this going to be the outcome of the final book?
