To save her brother, Meghan goes with childhood friend Robbie—the notorious Robin Goodfellow, or Puck—into Faery to seek her brother in the Summer and Winter fey courts. But a new kind of fey is rising, born of iron and technology, and poisonous to all of Faery. And as Meghan's journey to save her brother brings her into the sights of Prince Ash of the Winter Court, it also begins a quest to claim her destiny, intertwined with the fate of the dreaded Iron fey.
