Summary: To cold faery prince Ash, love was a weakness for mortals and fools. His own love had died a horrible death, killing any gentler feelings the Winter prince might have had. Or so he thought.
Then Meghan Chase—a half human, half fey slip of a girl—smashed through his barricades, binding him to her irrevocably with his oath to be her knight. And when all of Faery nearly fell to the Iron fey, she severed their bond to save his life. Meghan is now the Iron Queen, ruler of a realm where no Winter or Summer fey can survive.
With the unwelcome company of his archrival, Summer Court prankster Puck, and the infuriating cait sith Grimalkin, Ash begins a journey he is bound to see through to its end—a quest to find a way to honor his vow to stand by Meghan’s side.
To survive in the Iron Realm, Ash must have a soul and a mortal body. But the tests he must face to earn these things are impossible. And along the way Ash learns something that changes everything. A truth that challenges his darkest beliefs and shows him that, sometimes, it takes more than courage to make the ultimate sacrifice.
In the back of this book there’s an interview with the author. In one answer she states that she wrote The Iron Knight because her editor was a fan of happily ever after endings, which The Iron Queen did not really have, and so her editor convinced her to write another book to give Meghan’s story a happier ending.
And honestly? You can tell The Iron Knight wasn’t ever really part of Kagawa’s game plan for the Iron Fey series.
