Lili's plan backfires and she is believed dead, and exposed as a traitor to the Taelons. Liam and Augur are rescued by a Volunteer (a human foot soldier who has been augmented to a lesser degree than a Protector). Doors, on the other hand, is captured. Doors is able to cut a deal with Zo'or to give himself freedom while ensuring that his company can secretly resist the Taelons. The Volunteer is really one of his people, Renee Palmer, the new CEO of Doors International. Martial law is repealed and many of the Resistance members are returned. Lili is revealed to be alive, but in secret captivity, under Sandoval's control. He alters her DNA and sends her off into deep space. Liam and Augur continue to lead the resistance.
Though Doors proceeds to do work separately from the Resistance, Renee and Liam find their interests frequently overlapping, and occasionally assist each other. Their relationship gradually develops into a close partnership. At the same time, Da'an and Liam's relationship becomes strained, as Zo'or continues his ambitious plans from his position of leadership. Meanwhile, Sandoval seems to be working towards a clandestine agenda of his own, as he begins concealing information from the Taelons. Unbeknownst to anyone else, Lili arrives at the alien planet Sandoval sent her to, but because her perception is being altered, she does not realize this. The alien planet turns out to be the homeworld of the Jaridians, and Lili is tricked into delivering Taelon Inter-Dimensional (ID) travel technology to their leaders.
After the illusion ends, she realizes that she is in fact, on Jaridia, and is horrified once she figures out that the ID drives she unwittingly gave her new captors, are exactly what they needed to invade Earth. Time passes back on Earth, during which Jonathan Doors dies saving his son, and Renee continues to work with Liam. Lili eventually leaves Jaridia, bound for Earth, with a Jaridian named Vorjack, whose half-human, half-Jaridian child she is carrying. Their arrival complicates the plans of both the Taelons and the Resistance, particularly as Vorjack struggles with the atmospheric conditions on Earth. As the new hybrid baby is about to be born, Liam and Renee help Lili through a difficult delivery.
