Seconded. One of the best USUK fanfics I have ever read. The relationship is believable, there is an actual plot, and it's a fun read.

It's a very good fic. It shows Arthur's tsundere personality and the development of his and Alfred's relationship. Sadly it's still unfinished for now. It's based on the Artestella Artbook, if you have seen some scans, this one was based out of the Spades, where America is the king, England is the queen and so on. I recommend it for fantasy lovers.
