New Dean Koontz Novel Proves Book Critics Are Evil

A bad review must have really gotten under Dean Koontz's skin. His new book, Relentless, is about an evil book critic who gives a nice novelist a bad review — and then becomes a monster.

Actually, I haven't seen a copy of Relentless yet, but after reading the Publishers Weekly review, I'm dying to:

A bad book review propels this farcical thriller from bestseller Koontz (Your Heart Belongs to Me). Bestselling author Cullen "Cubby" Greenwich is mortified when Shearman Waxx, "the nation's premier literary critic," savages his work. Cubby manages to find the "syphilitic swine" at Roxie's Bistro in Newport Beach, Calif., where the author's six-year-old prodigy son nearly pees by accident on Waxx in the restaurant's men's room. In retaliation, Waxx threatens Cubby with doom and gets things started nicely by blowing up his house. With almost superhuman ease, the book critic keeps track of Cubby and his family as they flee for their lives. While some may take this as satire, the over-the-top villain's underdeveloped motivation and a jokey narrative tone that jars when juxtaposed with terrifying scenes of violence will leave others scratching their heads. By the time Koontz introduces a science fiction element, a lot of readers may have already checked out. (June)

I'm dying to know what the "science fiction element" Koontz introduces could be. Is literary critic Shearman Waxx actually a cyborg, or a genetically engineered superweapon, like in Watchers? An alien? The only hint I can find is this bit from the book blurb:

But Shearman Waxx isn't what Cubby expects; and neither is the escalating terror that follows what seemed to be an innocent encounter. For Waxx gives criticism; he doesn't take it. He has ways of dealing with those who cross him that Cubby is only beginning to fathom. Soon Cubby finds himself in a desperate struggle with a relentless sociopath, facing an inexorable assault on far more than his life.

What do you think "far more than his life" could mean? And more importantly, is Dean Koontz now expecting the Publishers Weekly reviewer to come blow up his house and terrorize his family?
