In Book III, after Kaelen's escape to the planet and the arrival of the mothership, there are more questions than answers. Samantha, now Commander of the station , discovers what the Array really is, and why the Overlords have not destroyed Jupiter Alpha One.

The overlords are coming, and as the walls fall, and the enemy floods in, humanity faces its final hours. The choices made here, on one station, in one moment, will echo across every world and every dimension. 

An explosive conclusion to the Portal Wars trilogy.
