Meghan Chase should be turning seventeen in twenty-four hours time, but things are a little complicated. One year ago, on her birthday, her brother Ethan disappeared and an evil, violent changeling was left in his place. Meghan learned that he had been snatched by faeries and she ventured into Nevernever, the land of the Fey, in order to save him.
What she discovered was the stuff of nightmares, a dark and sinister place full of malevolent and calculating Fey. She also discovered that she was the daughter of Oberon, king of the Summer Court.
In the space of twelve months, Meghan has fought and defeated the Iron King Machina; rescued her brother; become indebted to the Winter prince Ash and then fallen in love with him; discovered and then forgotten her long-last human father; reclaimed the stolen Spectre of Seasons, thus preventing war between the Summer and Winter Courts; and angered the Summer King sufficiently for him to ban her from Nevernever.
Of course, it doesn't take much to anger Fey royalty, and Ash too has been banned from Nevernever by his queen and mother, Mab of the Winter Court.
So technically, Meghan won't be turning seventeen because time moves differently in the Nevernever and Fey don't age. The Iron Queen begins with the promise of peace and normality for Meghan and Ash as, banished from Nevernever, they have no option but to return to Meghan's home and pursue life in the normal realm.
I have to admit, I was quite looking forward to seeing how faery prince Ash adjusted to high school and teenagers, but it was not to be because no sooner had they arrived at Meghan's home, were they attacked by spider hags sent by the false king of the Iron Realm. Realizing that she will never see peace until the Iron King is defeated, Meghan decides to fight him once and for all.
