Story Summary: It’s late summer 1997 and in the search for the remaining horcruxes, Ron, Harry, and Hermione are at Grimmauld Place hoping to find information about the locket. During their research, Hermione accidentally happens upon something quite different – something which leads Ron and Hermione on a visit to Gilderoy Lockhart, still in St Mungo’s. Suddenly they find themselves in Vienna, 1786, where Lockhart takes them to a party at the court of Emperor Joseph II, where Mozart has a riddle for Hermione to solve.
One of the more unique fanfics out there, I’m reminded of Jasper Fforde’s “Eyre Affair” series, thanks to the universe jumping and original story. This is a really cute 5-parter with Ron/Hermione emphasis. Definitely one of the better post-HBP I’ve read to date! Chapters are posted separately on an LJ: Part I, Part II, Part III, Part IV, Part V.
