The Truth in the Oracle, posted at omniocular for the "brothers and sisters" July challenge. The tale of how Andromeda and Narcissa patched things up, or as the summary puts it:

Kissing Cousins, a novel of lust and depravity among the Death Eaters, looks set to be next year’s best seller. The reputation of the Noble and Most Ancient House of Black is on the line, and there’s only one thing that its daughters can do about it; they’re going to have to talk to one another.
