Origin

After the raid on Mount Weather, Katy Swartz has been taken by Daedalus, the secret Department of Defense program that studies the alien Luxen and the hybrids made from them. Daemon Black will do whatever it takes to get her back, even if that means walking straight to the people holding her.

Inside Daedalus, Katy has to adapt in order to survive, and she begins to wonder whether some of what her captors tell her could be true. An unseen enemy is working against them, and Daemon and Katy may end up on opposite sides, with their future together in doubt. The book also explains what an Origin is.

Origin is the fourth novel in Jennifer L. Armentrout's Lux series, first published by Entangled Teen in August 2013.
