The Quality of Silence by Rosamund Lupton

There are books that are impossible to put down because the story is compelling, the pacing is brisk, and the suspense is palpable.  In this case, reading The Quality of Silence, I felt I actually had to take breaks because it was too intense, combining the threats of two implacable enemies, an anonymous but very sinister trucker who is following Yasmin and her daughter Ruby as they drive deeper and deeper into the vast and empty interior of Alaska in search of their husband and father, and the weather, cruelly cold and building quickly into a ferocious blizzard.  For Yasmin and Ruby are on their own, driving a "borrowed" semi north towards Anaktue, an isolated native village recently destroyed by fire.  The village is where Matt Alfredson was last seen alive.  They know they are being followed, but they didn't know why.  All Yasmin believes is that despite the police report, her husband is still alive but is now at the mercy of the Alaskan winter and won't survive unless she finds him.  Great stuff.
