I buy/view/listen to a lot of music video's (read, sorry night life) and this one was a disappointment. Sound varies too widely act to act. Couple of goosebump moments (I love the Mega-Guitars on Kansas City) but mostly a smorgas-bored of available talent putting in their charity work. Zero additives for the video freak and no real explanation of charitable intentions ever given. Borrow this from someone instead.
Negative

One of the best suspense books I have had the pleasure to read. The characters are a dynamic mix that make the story had to put down. You develop and understanding for the villian were you empathize with him while at the same time you feel for the hero and heroine to catch him. A must read for those who like suspense novels.

Positive
