Koontz seems to either hit the "time-travel" thing or miss it completely! He does a great job with this book. The narrator does a great job and the story itself is interesting. If you liked "Inglorous Basterds" this book has a little play on the history of the NAZI as well. . . NOT the same story line and different than Tarantino's story telling, but there is a bit of similarity in the stories. I would recommend this to ANYONE, but it is not Koontz's very best work. Entertaining and a good listen to if you are in the car long periods at a time.
