Does someone kwow a good fanfiction about Severus SDnape?

Kinda depends on what you're looking for, really. There's a few good slash fics, and Hermione pairing fics, and quite a few that are AU/AE. Many of the fics I really like are Snarry fics (with a few Hermione pairings thrown in) that are AU/AE.

But link is a quick a little one shot about McGonagall getting him out of jail after the the war. It's not a pairing (*shudders*) but more of a "she's his mentor" kind of a deal.

Okay, time for advertising my own stories !
Check my profile page here on FanPop. You'll find a link to my FanFiction.net page. I posted two stories focused on Severus, which have garnered good reviews :
- Sorely Missed and Sadly Remembered : DH compliant, describing what happened to his body after the last battle. I needed to mourn him.
- Too Much Love Will Kill You : AU, Severus/OFC pairing, packed with romance and action.
- The Blood Compact, just completed : AU, Severus/OFC pairing, with romance and action as usual.

Enjoy ! And leave reviews if you liked them.
