It seems like all her life, people have been calling Nightingale the "Valkyrie." Born amidst combat-an angel of the battlefield. But that's not who she is; she ventured into the Outlands with hopes of figuring that one out. She needed to know where she came from-who her parents were, if she has any family. What she finds out there, however, is far bigger than herself. With the help of her newest ally Jack, the only person to have left Bastion in centuries or longer, she discovers the truth behind the miasma that forced the world's population into the Council's ivory tower. It's a secret deeper than the Lab and E.C.H.O., it's a secret darker than One-Seven-Three; the Council has a hold on everyone who lives in Bastion, and Nightingale is the only one who can break it. But she's growing weaker by the day. Her mind deteriorates further with each use of her powers, and the nanobots that provide her healing factor are diminishing exponentially. If she's going to pull this off, she needs allies-fighters, rebels, she needs an army. She needs to be someone others can rally behind, she needs to be a symbol. Nightingale must become the Valkyrie. -- The conclusion to the science fiction/action-drama trilogy, Subject Nightingale, Volume 3 is a novel of approximately 61,000 words.
