Follows 'Star Trek 79: Invasion 1: First Strike', 'The Next Generation 41: Invasion 2: The Soldiers Of Fear', and 'Deep Space Nine 16: Invasion 3: Time's Enemy'.
For ages they have sought to claim our worlds. Now, at last, we take the battle to them . . .
Far from the Federation's desperate war against the invading Furies, the crew of the USS "Voyager" encounters something they never expected to hear again: a Starfleet distress call. The signal leads them to a vast assemblage of non-humanoid races engaged in a monumental project of incredible magnitude.
Here is the source of the terrible invasion threatening the entire Alpha Quadrant - and, for the Starship "Voyager", a possible route home. But soon there may not be any home to return to . . .
