Iceland, the 17th century. Young seminary student Eirik Magnusson longs to master witchcraft: to control the dead, cast spells, and subdue demons. And— to help ordinary people too. There’s only one difficulty: Eirik must become a priest. How to combine pastoral duties with magic and not end up burned at the stake? A girl named Disa in a small fishing village tames a sea monster and learns a terrible secret that shatters her life. She, too, dreams of adventures and sorcery. So it seems they are destined to meet. The story is based on folklore texts about Reverend Eirik Magnusson—a real historical figure, a priest and a practitioner of black magic.
