Reflecting Light, Part 1

All Mairead wants to do is keep her head down and survive her last year at Hogwarts. As a Partial Squib and the daughter of a notorious Death Eater, however, that is easier said than done. And with a mass-murderer on the loose and a new Defense Against the Dark Arts Professor who refuses to let her go unnoticed, Seventh Year is shaping up to be the most interesting of them all.
