Oh my gosh. Let me just say that I absolutely adore this story. I've yet to see a story like this on Mibba, so fantastic job on that! I love the whole concept of going back and stopping him, though if she actually does it, everything would change. James and Lily would still be alive, Harry would be insignificent. The only thing that would stay the same is Snape's loathig for Harry and undying love for Lily. But I'm assuming you already know this, which causes me to assume that she'll fail and something juicy will happen in return.
All of the factors of time travel linger in this story, so I can't wait to see what's bound to unfold. I must commemorate you on your writing. Each sentence is quite captivating and this story seems like it'll be a fast-paced thriller. Just the few chapters that you have up stand out quite a bit. I'm still trying to wrap my head around everything because your writing has left an impression on me.
