I have read all of his books to date and found that the only one I didn't like was 'Mr Murder' just couldn't get into that, though I did read it all I was not impressed.
I love the way he varies his writing, the book of his that has most surprised me was 'The Taking' ~ WOW did that ever give me the shivers LOL.
My most favourite characters were in 'Life Expectancy', think I spent alot of that book crying with laughter, and such a brilliant story.
But my all time top 10 of his books are:
Watchers
Strangers
Lightening
Life Expectancy
Midnight
Intensity
Velocity
The Sole Survivor
Whispers
The Eyes Of Darkness
