Book 4: Ivar 'the Boneless'

Prince Ivar 'the Boneless' Erikson of Kiev falls in love with and marries Princess Helga (Olga) of Chernigov. While taxing her people to finance a war against Denmark, the Chernigov 20 ambush and capture the prince and his retinue and threaten to execute him with the Roman 'Death by Sprung Trees' and, during negotiations, a knot slips and the trees tear the prince's lower legs off, creating Prince Ivar 'the Boneless', the Viking warrior that was carried into battle upon a shield. And this is their story.
