The Iron Prince Special Edition

The Iron Fey Saga continues…
Don't look at Them. Never let Them know you can see Them.
That is Ethan Chase's unbreakable rule. Until the fey he avoids at all costs begin to disappear, and Ethan is attacked. Now he must change the rules to protect his family. To save a girl he never thought he'd dare to fall for.
Ethan thought he had protected himself from his older sister's world-the land of Faery. His previous time in the Iron Realm left him with nothing but fear and disgust for the world Meghan Chase has made her home, a land of myth and talking cats, of magic and seductive enemies. But when destiny comes for Ethan, there is no escape from a danger long, long forgotten.
My name is Ethan Chase. And I may not live to see my eighteenth birthday.
