In the terrible winter of 1755-1756, Jon Steingrimsson travels through Iceland, dwelling in a cave in the south and writing letters to his pregnant wife in the north. He is under suspicion of having murdered her former husband and has been expelled from his position at his monastery. The south, however, is not a desirable place to be in: the glacial volcano Katla is erupting, shrouding everything in a cloud of ash, destroying everything in its path, and Jon is at risk of being buried alive in the cave. Despite this, he works hard to prepare for the arrival of his wife in the spring so that they can start a new life there away from everything. But the scandal of the suspected murder follows Jon all the way into the cave and tortures him there both day and night. Very soon, the general sheriff pays him a visit…
Reverend Jon Steingrimsson is one of the most remarkable people in the history of Iceland, and later became known as the ‘pastor of fire’. This unique novel portrays him as a young man in the dark times of the first sparks of the Enlightenment.
