The concept for this was truly inspired, and the interactions between Severus and the children were so incredibly well done. I could really see him fitting into the household and being a terrific father-figure.
I'm not generally a fan of Ginny, but I cannot stress how much I appreciated this characterization of her and the way the divorce was handled. All too often Ginny's portrayed as an unrealistic uber-bitch, and it has a tendency to sour the entire story for me, but you wrote this in a way that I can actually envision and enjoy.
