Sixteen-year-old Joan Sands is a gifted craftswoman who creates and upkeeps the stage blades for William Shakespeare's acting company, the King's Men. Joan's skill with her blades comes from a magical ability to control metal - an ability gifted by her Head Orisha, Ogun. Because her whole family is Orisha-blessed, the Sands family have always kept tabs on the Fae presence in London. Usually that doesn't involve much, but lately, there has been an uptick in brutal Fae attacks. After Joan wounds a powerful Fae and saves the son of a cruel Lord, she is drawn into political intrigue in the human and Fae worlds.
