People tend to stick up their noses at tie-in books - the titles created to expand the story of created universes. By and large, they do tend to be formulaic. This book proves that a tie-in book can be as good as anything being published. It has a great theme - sometimes, the most patriotic thing a person can do is commit treason. The opening line hooked me ("Her name, to which various people had recently been appending curses, was Ael i-Mhiessan t'Rllaillieu."), and I remember staying up all night to finish it. Come to think of it, I was hooked by the Romulan proverb in the preface ("Of the chief Parts of the Ruling Passion, only this can be truly said: Hate has a reason for everything. But love is unreasonable") It is, by turns, funny, exciting, and heart-breaking. If you have any interest at all in the original Star Trek universe, you should read this.
