A really good one, calming to read. Adds onto the stories but not in a way that is depreciating to the main events. A lot of good ones seem to have stopped or at hiatus.
This is a quick-pace novel which is alright, but the execution is bad, plus the harem stuff is also very weird later on. Adding it ruins the story too much. There are other fast-paced HP fanfiction which has been done right.
