What the Night Knows / Dean Koontz / 442 pages

"Not all magic is black magic...Most magic is about wonder and adventure, new horizons, and learning how to fly...This isn't magic.  This is the kind of weird stuff that's real."  Dark magic is definitely at work in What the Night Knows.  Detective John Calvino is determined to prevent a copycat re-creation of a ghastly murder spree that happened twenty years ago and involved his own family.  The target this time is once again his family -his wife and three children, and the perpetrator is the same - Alton Turner Blackwood - whom John himself killed 20 years ago.  John and is family battle evil personified; realize that "when the divine enters the world from outside of time, it manifests through children and animals"; and "what the heart knows trumps what the night knows."
