The hero, Matthew Cain, is someone you really want to appreciate. The plot is intriguing but the writing is slitted and really needs an editor or proof reader. The errors in grammar, spelling, and punctuation are aggravating and really detract from what could be a really good story.
It is a relatively short book that bogs down in uninteresting dialogue (as between Cain & Heather) and has errors in the story, e.g. Cain's plan is to cross a river to get to his target but when executing, he crosses a lake, then escapes across a river. It feels like the author is trying too hard to mimic the Jason Bourne storyline.
