The Enterprise recieves a distress call from a starship indicating they are being attacked and boarded, so they go to investigate. They soon discover that everyone onboard has been gruesomely murdered. They cannot figure out the rationale behind it.. .and then a discover one of the dead attackers: a Borg!
This only confuses them more, because this is not the Borg M.O. The Borg want to make you apart of their whole: another cog in their machine with no identity except that of the whole. They soon find a few of the Borg are still on the station and things get even stranger.
These Borg are fighting to defend each other, they show emotions, and they actually call each other by name. However, it is when Data, (an android incapable of showing emotion) becomes angry and kills one the Borg with his bare hands they strange is pushed beyond its limits.
Soon, in order to feel more emotions, Data flees the Enterprise with a captured Borg and set out to find "The One," (the person who helped these Borg change) and who has a plot against the Federation.
Now Captain Picard faces the challenge of having to fight one of his own officers and friends in order to save the Federation from these new Borg.
This book is a novelization of The Next Generation season six cliff-hanger and conclusion, so it is a very good story. The only problem I had with this book is that it is a Data story and it is not told from Data's perspective. If it was told from his perspective I it would have been a five-star review for me.
