Seconded. The relationship progression between America and England is really well-done, taking the time to show them growing closer to each other and why
they would be drawn to each other in the first place instead of just taking their Belligerent Sexual Tension
for granted without any true development or exploration like many other America/England fics do. And while the Kosmider plot does take a while to get fully into gear, it's definitely heading there as of now (Ch. 26) and the author also takes the time to build up realistic character interactions and dynamics among the cast, especially with America and France, Canada, Japan, etc. My only real criticism is that the fic has suffered from multiple Schedule Slips
already, which makes me anxious about whether it will actually be completed or not (especially since all the characters haven't even been introduced yet as of this time in writing).
