A Dance with Dragons
The Willing Maiden's cargo is twenty boys and eighty girls, slaves to be trained in the pleasure houses of Lys. It is captured by the Iron Fleet north of Yunkai in Slaver's Bay and the slavers are killed. Although Victarion Greyjoy frees the enslaved rowers, they are forced to join the Iron Fleet. Victarion divides the girls among his captains and drowns the perfumed boys. The Lord Captain sacrifices the seven prettiest girls to the Drowned God and R'hllor and renames the galley Slaver's Scream.
