Harry and Hermione realize their true feelings about one another during the time-turner adventure after saving Buckbeak and before saving Sirius. This leads to a different approach to the following events, where Harry fights Voledemort with Hermione by his side and blending more of Hermione's hard working approach. Story will feature a good Dumbledore, a good Ron. Will not be NC-17 to start with, but I expect it will eventually go that way, at least in bits, so rating it initially for safety.
