Rosie Black is on the run to save her family and uncover the truth.

Five hundred years into the future, the world is a different place. The Melt has sunk most of the coastal cities and Newperth is divided into the haves, the "Centrals"; the have-nots, the "Bankers"; and the fringe dwellers, the "Ferals". Rosie Black is a Banker. When Rosie finds an unusual box, she has no idea of the grave consequences of her discovery. A mysterious organisation wants it - and will kill to get it. Forced to rely on two strangers, Rosie is on the run. But who can she trust? Pip, the too attractive Feral, or the secretive man he calls boss? From Earth to Mars, Rosie must learn the secrets of the box - before it's too late.
