What this book is about
Cubby Greenwich's novel gets one devastating review from a critic known as Shearman Waxx — and then the critic begins trying to kill him. Koontz's thriller is deliberately preposterous, combining family adventure, bizarre menace, and his signature warmth. Not his darkest work, but effective as a thriller with genuine scary sequences.
