Karmin Cox is unique in the fact that she can't feel pain. Ever since she was young she's had a congenital insensitivity to physical pain. She's never had a normal life, and never will, but once she gets to high school she believes her life is as average as it's going to get and though she wishes it to stay that way forever, it isn't meant to be. One night while she's getting a midnight snack, she gets a surprise visitor who will completely turn her life around and make it anything but normal.
