Book #4

Book #1 The Iron King, Book #2 The Iron Daughter, Book #3 The Iron Queen. To cold faery prince Ash, love was a weakness for mortals and fools. Until half-human, half-fey Meghan Chase won his icy heart and bound him to her with his oath to be her knight. But Meghan is now the Iron Queen, ruler of a realm where no Winter or Summer fey can survive. With an unlikely band of allies, Ash seeks a way to honour his vow to stand by Meghan's side. To stay in the Iron Realm, he must have a soul and a mortal body. But the tests he must endure to earn these things are impossible. And along the way, Ash learns that, sometimes, it takes more than courage to make the ultimate sacrifice.
