Title: The Iron King
Author: Julie Kagawa
Publisher: Harlequin Teen
Release Date: February 2010
When sixteen-year old Meghan Chase's little brother is abducted by the Unseelie Court, it throws her for a loop; she never believed in faeries. But with her best friend Robbie Goodfell—who turns out to be the infamous Puck—by her side, she ventures into Faeryland to get him back, only to discover it wasn't the Unseelie fey who kidnapped her brother after all, but a brand new species of faery led by Machina, the Iron King. These fey, born from the dreams of technology and progress, are completely immune to iron, and are a deadly threat to the courts of Summer and Winter. In the search for her brother, Meghan discovers her own faery heritage, falls in love with a dark prince of the Unseelie court, and confronts Machina in his realm of iron, to save herself and everyone she loves.
It is about fairies. I love fairies. I really want this book. It is also a tenner book and Julie is so nice.
