Sally Brown is a genius. She is not happy at being uprooted yet again. Her father's new job as lead engineer at Billings Shipyard means a new town, a new home and a new school. But soon, Sally teams up with IT geek, Henry, and budding journalist, Shelia, and life takes a turn for the better. However, not all of the staff at Billings Shipyard are as they seem and soon her father, and in turn Sally, are embroiled in a case of international espionage, treason, murder and abduction. How far does the corruption go? Who can they trust? It doesn't take a genius to see they are all in great danger.
