Truth and the Snake

Aletheia's pureblood parents tried to cure her scandalous goodness by locking her up and starving her for weeks. Finally free by getting into Hogwarts, her quietness does not let the Slytherin girl go unseen. She has gifts Severus Snape is not ready to ignore, and one thing she doesn't know, is where this is going to take her. To hell and back, from 1st year to the end of the War.
