I'm going to second this. The fic starts off relatively strong- the prose is relatively limited but it actually allows the story to have a really interesting noir vibe to it, effectively building intrigue and creating a really interesting and mysterious atmosphere. The story does some interesting work when it comes to blending together memories and reality, something that (if slightly underutilized) really comes home in the second half of the narrative.
The story in general does some really interesting reflection on the past and how it collides with the present- of a Harry Potter that is unsatisied with his life, but knows of no other true life to live, and his struggles with coming to terms with his own unhappiness and his struggles with learning what to do about it. The sharp contrasts between younger Harry's idealism and current Harry's sense of utter entrapment ("ennui" is indeed a good way of describing it) is fantastically done.
The first half of the story isn't necessarily about the mystery of Draco's disappearance, despite the synopsis; it's far more about Harry's struggles to really figuring out a way to escape his current circumstances and find a true home for himself, and it's in those parts of the narrative that the story really shines, and is a deeply compelling adventure.
The first arc of the story resolves in a way that holds together and is compelling enough, and you get to some of the best stuff of the story; really seeing Draco and Harry navigate each other's boundaries in this new life they have together, the new connections they share, and building up their dynamic. There's a lot of really interesting character building here, and the characters play off each other absolutely effortlessly.
There is a section of the second act that is just Harry and Draco driving, with no particular destination in mind, and you really get that sense of an aimless road trip, just travelling just to travel, and examine the world at the various stops that they visit. And each stop manages to add something to the characters, their experiences, and their relationship with each other.
Harry is a deeply relatable character while still feeling like a realistic outcome from Rowling's narrative, and everybody else is quite effectively captured too, with thoughtful analysis and contrast done between the canon selves and genuinely impressive character work done here. A bit more could have been done in a couple cases- Astoria could have been a bit more developed mainly- but that's a quibble. The characterization is, in general, absolutely fantastic.
The prose has two forms, the more sparse style of the first arc, and the more detailed and loving descriptions of the second arc, that really bring backgrounds to life. But the two flow together basically seamlessly, to the point that I'm uncertain I could point you to where one ends and another begins, and both are absolutely fantastically written.
There is absolutely no bashing, despite there indeed being Harry/Ginny in the story; Harry and Ginny's relationship is actually an important part of Harry's character flaws and his arc, and Ginny is portrayed wholly sympathetically, even if she doesn't have that much of a role.
This is an absolutely stellar story that you absolutely don't have to be a Draco/Harry shipper to enjoy, as somebody that isn't one herself. Read it.
