The Iron Daughter by Julie Kagawa
This story picks up where the Iron King ended. Ash, a prince of the unseelie court is leading Meghan Chase, half human half fey, daughter of King Oberon, back to his winter court. Meghan is hurt and confused by Ash's coldness towards her. Meghan doesn't know who to trust anymore. Queen Mab doesn't believe their story about the Iron Fey. When Ash's brother is killed and the Sceptor of Seasons is stolen by the Iron Fey, Ash and Meghan have to flee the unseelie court and try to get it back before a war is fought between the winter and summer courts. Julie Kagawa does it again! This story is captivating from beginning to end. I can't wait to read the next one. I highly recommend this series.
