Some people have already mentioned the Lee Child's Jack Reacher books and I can only agree they are brilliant and you do get hooked on them (there's 10 of them so far). He does the American thriller better than any American I know. Stephen Leather is another really good thriller writer, The Chinaman is addictive.
As an aside does anyone ever have the same problem I have and get a couple of hundred pages from the end of a book before I go away and then just don't get the chance to finish it and end up lugging it away with me just to finish it - usually on the plane! Very frustrating
Also find although I normally buy books before I go to the airport I usually find I buy another 1 or 2 at the airport as it's all part of the holiday experience. Must like wasting money. Don't always end up reading them before I get back either.
Martina Cole- must get around to some of her's as so many like them. Have to admit I dismissed them as Chicklit as they were written by a woman and didn't look like thrillers. The saying really is true never judge a book by the cover!!!
