Changeling Magic

For about five seconds there, my life was perfect. The fae king finally allowed me back into the magical Realms of Faerie, and his arrogant knight, the Hawk, was actually thawing towards me.
I should have known it wouldn't last. When I get back to my childhood home in Autumn, my mother's gone, our house abandoned. Not exactly the homecoming of my dreams.
Then an injured stranger turns up in the mortal world, claiming to be my mother, but she dies before I can question her. If I want answers, I'll have to find her killer. And guess what? The killer is looking for me, too-but not for a friendly chat.
Everyone is keeping secrets, and I can't even be sure who I am anymore-or how dangerous the truth will be when I finally uncover it. Just as well the Hawk has elected himself my protector. Keeping me alive will be a full-time job.
