A Chinese freighter attacked. A sabotaged passenger jet crashed in Quebec. And high overhead an E-4B Nightwatch, America's fortress-in-the-sky, sees all.

With nations shifting to high alert, Miranda Chase lands once more in the midst of the fray. But first she must fight battles of her own. Can she conquer the emotional chaos her autism unleashes amid the loss of her past? In time to save her team? —And avert the disaster playing out under the Northern Lights?

A tale of high adventure, airplanes, and espionage.
