Stephen's work definitely deserves a read. Given just a sample of his work makes you want to finish the book to completion.
I had nothing to nitpick throughout the entire reading experience. He has clearly thought out his story and tone of the overall work.
The Sleeping Man character only makes you want more, I found myself captivated by his character and in all honesty wish I had thought of this myself.
Buy THE SLEEPING MAN, it has a good future ahead of it.
