K. McKenzie (USA: OR) (2007/11/06): I am not sure if I could say that I loved this book, but it would be fair to say that I couldn't put it down. On brief examination Koontz's characters in this book would seem impossible, yet his eerie ability to bring them to life kept me riveted.
Pixie (USA: KY) (2008/09/11): This was a real page turner! Loved it!
C. J. Muir (USA: CT) (2009/05/31): As the first book by Dean Koontz that I've read, I found it to be a very addicting read.
saharasnow (USA: SD) (2010/09/02): This was an AWESOME Thriller, kept you wanting to turn the page. Such a gifted & extremely descriptive writer. This is a must read! Loved the story line, different yet Plausible...I felt like I was there the entire time, holding my breathe.... Really a spine tingler
