Some dark undercurrent woe

As a new menace arises in the form of a pesky Ministry official poking her nose into Harry's business, the wizard finds himself owing Lucius Malfoy a favour. It's simple really—Harry just needs to support Malfoy's daughter-in-law in her quest to win the upcoming elections. It ends up being a lot more than that. In more ways than one. SLASH, HP/LM.
