Before his encounter with Ealdorman Leofwine on his fateful trip to Shetland, King Swein first had to wrestle Denmark from his father's kingship and make his own name as a warrior of great renown.

This side story to the Earls of Mercia series tells of the early years of King Swein's reign, his first raid on England, his encounter with Ealdorman Leofwine and his quest to once and for all kill Olaf of Norway, culminating in the mighty sea battle of Svolder in 999.

Swein, the Danish King is a companion novella to the epic Earls of Mercia series and should perhaps be read following Ealdormen, book 2 of the Earls of Mercia series.
