This apocalyptic thriller had me staying up way too late on work nights! It even had me sneaking around my house with a flashlight after everyone else was in bed, making sure there were not lurking monsters around every corner... And I am a big-time horror lover! The sense of creepiness that this book oozes really sticks with you.As my first Koontz book (I don't know why), this book will definitely not be my last. Although the author's almost sentence frequent use of metaphors and similes annoyed me at first, I became used to it after a couple of chapters. I think this tendency to extreme description probably helped pull me more into the story. This book is one I will keep on my shelves to read again and again.
