By, Ally Condie
Poe Blythe is the young captain of her failing city's last mining ship, travelling the Serpentine River and dredging up gold.
But it isn't gold on her mind. Two years ago, river raiders robbed Poe of everything. And she wants revenge.
As she navigates the treacherous waters and realises there's a traitor among her crew, Poe is forced to confront the dangerous truth about why she has been sent on this journey - and reckon with who she has become.
