The Iron Traitor by Julie Kagawa
The Iron Fey: Call of the Forgotten # 2
This book gives readers enough back-story not to get lost, but it would help tremendously if you read The Lost Prince first. I think that I would have enjoyed this series so much more if I had. This book has a fairly good stand-alone quality, but I felt like I was missing some of the picture not reading the first book.
The characters and plot were unique and give the story that extra something special.
All in all, I enjoyed this book but would highly suggest reading the first book in this spin off series first!
In the real world, when you vanish into thin air for a week, people tend to notice.
After his unexpected journey into the lands of the fey, Ethan Chase just wants to get back to normal. Well, as "normal" as you can be when you see faeries every day of your life. Suddenly the former loner with the bad reputation has someone to try for-his girlfriend, Kenzie. Never mind that he's forbidden to see her again.
But when your name is Ethan Chase and your sister is one of the most powerful faeries in the Nevernever, "normal" simply isn't to be. For Ethan's nephew, Keirran, is missing, and may be on the verge of doing something unthinkable in the name of saving his own love. Something that will fracture the human and faery worlds forever, and give rise to the dangerous fey known as the Forgotten. As Ethan's and Keirran's fates entwine and Keirran slips further into darkness, Ethan's next choice may decide the fate of them all.
