I, Immortal — M.J. Rutter

Imagine being told you will live forever, that you are not alone, if you passed them in the street you would never know, they are everywhere. Hidden among us, trying to be normal, when they are anything but. Amelia is immortal, she was born in 1659 and abandoned by her mother and left on the steps of a convent. Where even the nuns are weary of her, she feels she is different, the animals won't come near her, even when the wolves descend they are afraid of what she is. Why?
