Black Betha rode the flood tide, her sail cracking and snapping at each shift of wind. Wraith and Lady Marya sailed beside her, no more than twenty yards between their hulls. His sons could keep a line. Davos took pride in that. -George R.R. Martin, A Clash of Kings

A Turn of the Tide is the fourth Chapter Pack in the A Song of the Sea cycle. As each of the Great Houses maneuvers its navy for utmost impact, their rivals respond. As the Lannisters use any means necessary to retain their hold on the Iron Throne, the Krakens of Greyjoy raid the coasts, the Martells hunt for new strategies to claim their vengeance, and House Baratheon seeks new life after their losses on the Blackwater. Meanwhile, the Starks turn their attentions toward The Wall and the threat from the north as the Dothraki follow their Targaryen queen to conquest in the lands across the Narrow Sea.
