I've read and re-read this fic from pretty much the time it was published and my love for it only grows with each re-read.
The characters are all written on point. No one is side-lined or made to appear as unimportant or are simply there just because it's expected that they are, but they don't end up doing anything. Everyone has a role to play and has time in the spotlight. The relationships (pre-existing or new) that are formed and developed over the course of this fic is beautiful and heartfelt. You can feel as you read just how much these people care for one another, even when they are trying to hide it behind walls and/or snark.
The writing is delightful and witty. The dialogue flows naturally and the amount of sass and snark that is cramped into this fic is hilarious and unforced. The description of events, locations and battles are amazingly detailed without being overly wordy and complex.
This fic will take you on a rollercoaster of emotions, you will laugh, you will cry, you will want to throttle several people because of the horrid things they have done, and you definitely want to give the characters many, many hugs as you wrap them in blankets as you give them hot chocolates to drink.
It's a masterpiece of fanfiction writing and I would recommend it to anyone who wants to read a high-quality Avengers fic. Even if you're not a Stucky fan, there is enough humour, action and the presences of other characters that you won't be overwhelmed by Stucky feels. But in saying that, all the Stucky scenes are beautifully written and heartfelt (this is the fic that actually made me go 'yeah, you know what, I ship these two.) and even though you are reading their scenes from Tony's POV, you still feel so much in regards to these two and you just want them to be happy and safe together.
Read this fic, you will not regret it.
