An excerpt:
Another character who has come a long way in his Starfleet career is Worf, currently serving as first officer of the Enterprise. Throughout TNG, Worf was characterized as being quick to fight, and often rushing headlong into combat without giving adequate thought to the consequences. Now, after having served for many years in Starfleet and even a stint as ambassador, we see a more mature and thoughtful Worf. When Q appears, it is Worf who suggests the tactic of ignoring him completely, much to the surprise of Counselor T’Lana who believed she had the Klingon pegged as a hothead. The fact that he has become much more cool-headed has shown that he makes a very good first officer. Also, the experience he had traversing quantum realities in the TNG episode “Parallels” comes into play in this novel, as the Enterprise faces a similar situation at the climax. It turns out, of course, that Q was responsible for the events of that episode, knowing that the knowledge Worf gained would come in handy at this juncture.
