Hi. I'm not sure if this the right place to ask but I'm looking for a fic that I read a while ago. It was a human AU and C and A knew each other through some book forum, then they meet irl but they don't know who the other is. Things go pear-shaped but they keep talking on the forum while also slowly patching things up irl and falling in love. I think C has a mental illness and becomes slightly obsessive. I remember Harriet being his sister and looking out for him, and there was a scene at a fair or something where C was being controlling of A and Warlock came in and let C know by using a codeword that included 'Apples' and thats how A figured out C and his forum friend are the same person...
Hello!
I believe you are looking for The Bookshop Around the Corner by mordelle (M)
Anthony J. Crowley is a cynical book critic who doesn't believe in love. Aziraphale Z. Fell, is a bookshop owner and romance novelist. Aziraphale's godson good-naturedly sends Aziraphale's romance novel to the famous critic, who writes him an unmerited, awful review. Both are enamoured with an anonymous friend from a respectable book forum. Little do they know they have unwittingly fallen in love with each other in their sanctuary of anonymity.
