Mirabilis is a fictional retelling of the life of Christina the Astonishing, the outrageous twelfth-century saint who died three times, was imprisoned by her own sisters, ran riot through the towns of the Low Countries, and rose to become the spiritual advisor of the Count of Looz. Part medieval bag lady and part spiritual superhero, Christina defies the possibilities available to a woman of her time and station to carve out an unforgettable and controversial path to sainthood.
