Query: Captivating and Scary!!!!

This is one of my all time favorite books. It's my second favorite by this particular author("Creature" is my fave). The book itself is much like all of Saul's previous works(close knit family gets into trouble within a small, close knit town), however, this one seems to jump out at the reader, mainly becuase of the advances in DNA technology in the recent years. The entire book is about the DNA reconstructuring of humans in the womb, and I personally feel that this isn't too far off in the real world. A good plot becomes scarier when it can be true.
