Query: Starts out slow, but then becomes an action packed thrill ride!

The first few chapters of Behind the Dark CurtainStart out kinda slow, but then the book getsreal action packed with tons of thrills fromall sides. At first I thought this would just beanother Da Vinci Code, wrong, this is somethingelse all together. Adam W. Gibson is a great writerand I can't wait for the next book in the series.
