Avengers Fanfic/Fanworks Search Community

1) I am looking for a specific fic that I read probably 2-3 years ago, but I can't remember much about it so finding it is proving a challenge. Basically what I remember is that it began before all of the movies going throughout Tony's childhood and then into the movies (maybe??).... Steve was still frozen in the ice and I think he was a ghost (or something like it) who only Tony could see. It was a slow build Steve/Tony fic and I remember something having to do with Obadiah Stane, but that's it really. I think it was a longer fic, probably at least 20k-30k words and I am fairly sure I read it on AO3.

2) Specific Themed Recs - I am in the mood for fic somewhat along the same lines as the specific fic I am looking for... basically, I want AU fics where Steve and Tony meet before the Avengers. Maybe Steve was de-thawed early and helped Tony when he was in Afghanistan, or more where Steve is a ghost, has a soulbond with Tony so they interact while Steve is in the ice, etc. Just basically fics that have a younger Tony interacting and falling in love with Steve long before, during or soon after he becomes Iron Man.

Thanks in advance for the help!
