I couldn't help but think that this book was like the younger, less intelligent sibling of Velocity (one of Koontz's masterpieces). The main character was a tad bland and enigmatic at times that left you more bored than frustrated and more anhedonic than enthused.
The position the main character is forced into is morally disrupting, but hardly holds a candle to Velocity's emotional torture.
The main save of this book is the saddistic bad guy, that you can't help but like at times due to his dark humour and depth.
The climax isn't bad, it's just like the characters got a bit tired after the entire book was a big game of 'chase me!'
If you've already read Velocity, give it a go, it's a good 'on the bus' book and has its moments. If you havn't read Velocity, go read it first, or you'll regret it.
