Margaret Mellow has a crystal-shaped birthmark on her back that glows on her birthday. She's kept it hidden from everyone except her parents and she's always wanted to know more.

Why does she have a glowing birthmark?

She's a mystery case not even the best doctors can figure out. When she faces challenges like never before, she finds herself in a reality she never thought possible. It's a world far from where she's known and only time will tell if she accepts it.
