A fantastic must read story! A sort of what if, that you will love to read!
This is less of a review, and more of a comment for the author.
This is probably the best fan fiction that I've ever read. I felt satisfied enough at the end of reading this that I decided to make an account. I hadn't ever considered making an account on this website until now. I love that the main focus of this was character development, and the story that you laid out, rather than the sexual scenes being the main focus of this fiction. Keep writing. Keep to the tastefully adult stuff.
I did notice some gramattical errors, but they didn't detract from the reading experience very much. I still loved it, and encourage you to keep writing.
You really are the Angst queen arnen't you? How could Hermione be so reluctant to be intimate with the man she loves and has children with, even though her mind is from 10 years in the past. It just doesn't make any sense.
