In book 4 of The Strongbow Saga, the victorious Viking army has returned to Denmark from Frankia, after having captured Paris and extracted an enormous ransom from the Franks for leaving their kingdom in peace. Now Halfdan, with the aid of Jarl Hastein and his men, is ready to bring Toke, the chieftain who murdered Halfdan's brother Harald, to justice. But Toke proves to be a cunning and ruthless foe, and as Halfdan sees his quest for vengeance turn into a long and grueling pursuit eastward through Danish waters and across the Baltic Sea, the pursuers will soon find themselves to be the ones in danger.
