What The Night Knows starts right into the creepiness.  At the opening of the book much backstory has already occurred.  The details of the past will begin to become clear as the story progresses.  We are immediately introduced to our hero, a man with a deep foreboding brought on by recent events.  A terrible murder spree has just taken place with eerie similarities to a similar crime 20 years ago.  What could their connection be?  Koontz weaves a nightmare scenario that gets scarier and scarier.  Word by word, chapter by chapter, he turns the screws of our fight or flight instinct until it's too late to flee.  Having read almost every Koontz book this is certainly one of his best.  This one is genuinely scary.  The book has really stuck in my mind.  Scenes from throughout are very memorable.  This could easily be a story where the pacing lags but Koontz pours on the gas.  The villain here is awesomely frightening.  He has quickly become one of my favorite bad guys Koontz has created.  The book kept me flying through the chapters as the evil builds and encompasses our heros' lives.  I found the family's children fun and the characters well done.  This book is a darker novel than the more recent ones.  I agree with some reviewers that it has a darker atmosphere like Hideaway.  I would recommend this book to anyone looking for a creepy, scary read and people interested in an introduction to Koontz' supernatural thrillers.  I also highly recommend the novellaDarkness Under the Sun (Novella): A Tale of Suspense, available in Kindle version, which introduces the villain here in a separate storyline that won't ruin the story told here.  This one is excellent. and I am eagerly looking forward to the next Koontz.
