The author of the “thrilling, unnerving, clever, and beautiful” (Fredrik Backman) Wolf and the Watchman series presents a new historical series that takes us to medieval Sweden to unravel one of the country’s most infamous murder mysteries.

1434: The Kalmar Union is cracking at its seams as a rebellion, led by miner Engelbrekt Engelbrektsson, erupts in the north. Sent by his status-seeking family, young Måns Bengtsson must win Engelbrekt’s trust no matter the cost. Back at his family’s castle, his mother, father, and sister wait for news of his success. One is lost in longing, another forges plans for the throne and crown, and one might finally have the opportunity to rise from her brother’s shadow.

As the fifteenth-generation grandson of Måns Bengtsson, Niklas Natt och Dag expertly delves into his own family history to reveal a chilling and compulsively readable mystery.
