Fantastic premise and overall a diverting read except for the author's annoying use of the word "still" over and over and over throughout to indicate counterpoint. "Still, Monk couldn't help but feel ..." " Still, Gray wasn't sure ..." Now that I've mentioned it to you, you'll start counting the number of times he uses it. And there were numerous places where I (a fantasy and sci fi fan no less) could simply not suspend my disbelief and laughed out loud at the absurdity. And what's with the hand SOS thing at the end? That was a preposterous way to leave open for a sequel I suppose.
To compare this book to The DaVinci Code is to compare Ripple to Opus One. I listened to half the book thinking that it had to get better and that I had to get my monies worth. Finally, I couldn't take it any longer due to the incredibily thin character development and unbeleiveable plot which seemed to get worse as the book went along.
If there is an abridged version of this book and you half to read it, then don't bother with being bored for 18 hours.
A cold shower would be a better bet.
