Here is the summary of the book:
My name is Meghan Chase. I thought it was over. That my time with the fey, the impossible choices I had to make, the sacrifices of those I loved, was behind me. But a storm is approaching, an army of Iron fey that will drag me back, kicking and screaming. Drag me away from the banished prince who's sworn to stand by my side. Drag me into the core of conflict so powerful, I'm not sure anyone can survive it. This time, there will be no turning back.
So Ash and Meghan have been sent to exile never to return to nevernever ever, well until announced otherwise at least by their sires. Their crime fall in love with one another. Its a rule or should I say law that a Summer Fey and a Winter Fey are not meant to be together. But danger still lurks around the corners. The false iron king has declared open war on the Seelie and the Unseelie Courts and as they myth goes these two 'oldworld' feary can't even turn a hair off from these abominations (iron fey), simple iron does not bode well for them. So naturally Ash, Meghan and Puck (who was later also exiled by the Erlking) are called back because well they are the only ones or better yet Meghan is the only one who can enter the Iron realm without being poisoned by its effect and as her knight and lover (Prince Ash) and her best friend (Puck) tag along as well on this new quest to put a stop to the false king's advent. With loads of help from yours truly Grimalkin.
The Iron Queen *kicks-butt* literally. Its not only the level of details that gives it a positive leverage and staying true to the old saying but its only about the way the characters co-relate with one another. This book is definitely about Meghan, about how much she had grown in the span of time she spent in the feary. Witnessing so many things that normal humans are meant too(well she isn't normal, she is half-fey) and growing into a sensible and an unselfish Queen. Towards the end of this book Meghan finally comes to embrace her destiny, which is a rather huge task to accomplish. As well as uniting them all and accepting the good and the bad.
Not just Meghan but Ash and Puck play a huge role here as well. Now I'm always for Team Ash since it was blatantly obvious from the start and well he is rather gorgeous as well....well Puck could have gone there too but he waited too long to make his move and I have to say he sound rather like a best friend material to me. Both are on a constant change in the character scale. Ash out of the bondage of the Winter court has started to show another side of him or has finally decided to drop the indifferent mask he wears all the time. He is now well rather very sweet, he cares a lot for Meghan. He is more open now and rather very lovey-dovey too. That is definitely a 360 degrees change we get to see in few. The extent to which Ash and Meghan would go to be together is rather heart-wrenching(definitely not another Romeo and Juliet....thank God).
Puck on the other, as mischievous as ever (he is Oberon's jester after all) but also shows a certain level of maturity. He knows he has got no chance with Meghan now and has decided to go the way of 'her happiness is my happiness'. Pretty smart of him and very sacrificing. He could easily fight for her love with the elusive Ash but he knows that Meghan loves him(Ash) and would never be able to return his feeling.
Three of them - Meghan, Ash and Puck along with Grim journey to the Iron realm and stop the false king before the whole of the nevernever is destroyed and helping Meghan along the way as she struggles with both her summer and iron powers. Since I have already finished 'Summer's Crossing' as well, I'd say this one was the best yet. Julie Kagawa really has done it again because like a fairy this Iron Fey series manages to enchant you and you can never break free off it strong hold.
