Ice Station

Ice Station - Matthew Reilly This was the first of the Shane Schofield (a.k.a. "Scarecrow") novels.
Everything is non-stop action, going from one over the top situation to another.
There's no clever plots-within-plots, or sudden twists. Each situation comes on at full speed and is usually dealt with in the same way.

As it's one of his earlier books, there's lots of italics to show how awesome things are. It may turn some people off, but it's always been one of the things I liked about these stories.
