Magic lies at the heart of Cassaforte, medieval city of bewitchments and intrigue. Cassaforte is home to sixteen-year-old Risa Divetri, whose fate is about to be decided by the gods.

Risa has led the sheltered life of a nobleman's daughter, but soon she plans to leave home to study the family craft-creating enchanted glass objects. When the gods are consulted to determine which school she will attend, the impossible happens: Risa remains unchosen. The rejection sends Risa into a spiral of shame, anger, and confusion. If she's not meant to be a glass maker, what will she do?

But when Cassaforte's age-old magic begins to unravel and dark forces threaten the kingdom, Risa's fiery spirit and untapped powers take her on a perilous journey—one that will lead her to her true destiny.
