The world was called Montefiore, as far as she knew, and from her aerie on every side all the world descended. The year is 1502, and seven-year-old Bianca de Nevada lives perched high above the rolling hills and valleys of Tuscany and Umbria at Montefiore, the farm of her beloved father, Don Vicente. There she spends her days cosseted by Primavera Vecchia, the earthy cook, and Fra Ludovico, a priest who tends to their souls between bites of ham and sips of wine. But one day a noble entourage makes its way up the winding slopes to the farm - and the world comes to Montefiore. In the presence of Cesare Borgia and his sister, the lovely and vain Lucrezia - decadent children of a wicked pope - no one can claim innocence for very long. When Borgia sends Don Vicente on a years-long quest to reclaim a relic of the original Tree of Knowledge, he leaves Bianca under the care - so to speak - of Lucrezia. She plots a dire fate for the young girl in the woods below the farm, but in the dark forest there can be found salvation as well ... The eye is always caught by light, but shadows have more to say.
