Once Upon a Time Turner by AbstractConcept/
the_con_ceptIt's Snarry and I've totally fallen in love with it :)
Author's Summary: Snape decides he isn’t happy with the end results of the war, and starts over with a clean slate-and Harry Potter. But though he’s determined to change things, he isn’t expecting the biggest changes of all-the ones to himself.
Apart from a Harry whose exposure to the wizarding world and education has been dictated by Snape (*g*), my favourite aspect of this story (so far, as I'm only on chapter 5), is that you can see the direct contrast between canon Severus Snape (from book two-ish at the point I'm at) and futureSnape. It's made me actually quite dislike canon Snape, noooooooo, I like his complete horridness, what has this story done to me??? :)
Anywho, I highly recommend this fic, go forth and read!!!
