Lent

by Jo Walton

In Renaissance Florence, Girolamo Savonarola is a Dominican friar with the gift of prophecy and the ability to see and banish demons. After Lorenzo di Medici dies in 1492, Girolamo gradually becomes more and more involved in politics, eventually culminating in his execution in 1498, and subsequent damnation to Hell.

He then finds himself in 1492 Florence again, and begins trying to change history.
