Okay so I've never read a QAF fic before but you kept talking about Endeavour so I had to give it a try and I'm hooked! It's soooooo bloody good. Thanks for the great rec!
yes, it’s amazing
once you finish that read Inescapable and Things I Cannot Change
they’re both also amazing
but they’re super long (over 100,000 words each)
but they’re totally worth it
