The synopsis at the back of the book does not prepare you for the fright you will feel when you read this book. Koontz does not specialize in gore, choosing instead to bring to the fore of our minds our hidden fears or insinuate fears we did not know we could conceive. He is a genius at psychological manipulations and you will know visceral fear. The plot is a great one and moves at a galloping pace. This book's basic premise seems simple enough, but its implications are spellbinding, heartbreaking and truly fearsome. As usual, the characters are ones you can relate to, and feel compassion for, even pray for. The compulsion to peek at the end before you reach it will at times be overwhelming, just to set your mind at ease, but you'll be glad you built up to the climax. First rate!
