(AU) Hermione Granger's dissertation advisor and even her parents think she's crazy to suggest Britain may once have had magic, but a concerned DMLE sees her research as a risk to the Statute of Secrecy and sends a messy-haired, green-eyed Auror to investigate. Her tenacity combined with his fast thinking uncovers a conspiracy...
(Regency AU) The formal ball Harry's hosting is even worse than he thought it would be, but he's pretty sure he's found the perfect place to hide from his adoring (this week) public...until the curses start flying. In the darkness of Potter Manor Library, Harry and a mysterious witch will finally face the hidden scars of the war and either accept damnation or find their own light.
When Draco goes missing on an Auror operation and they don't want to spare the resources to look for him, Narcissa hauls Harry out of his depression to find her son. The decrepit Greengrass Manor conceals far more than Draco's fate, though, and the old enemies become unexpected allies in a fight against the Ministry, Death Eaters, and a dead man's hatred.
Harry doesn't necessarily expect a polite "thank you" after saving Daphne and her sister from falling to their deaths, but he definitely doesn't expect the stream of verbal and magical curses he gets instead. His surprise is nothing compared to hers when her curse fails, though...
