The Out of the Gray — Patricia Gilliam

When a terrorist organization called the "Earth Independence Party" targets Hannaria's Ambassador, two teenagers find themselves caught in the situation at different vantage points.
"Alex Verin" is the son of an EIP representative who doesn't want to follow in his father's footsteps of being trapped in a web of political manipulation and corruption. "Rica Miller" is the adopted daughter of an engineer and nurse who finds out at age thirteen she isn't human but Hannarian.
"Alex" must decide between his family loyalties and saving the life of an alien he's been taught to fear and hate while "Rica" searches for the truth of what really happened to her biological parents.
