Ok Deani, you said if someone would rec, you would read. So here are some recs. These are Harry/Snape (Snarry to those of us in the fandom) and all are well written. This is just a small taste, if the pairing suits, I'll point out more, if not, on to Harry/Draco. And I'll look for some Blaise eventually. :)
Icarus
Primer to the Dark Arts
Harry learns he is to be given private (and secret) tutoring in the Dark Arts to protect himself next time he meets Voldemort. His teacher? Professor Snape. Features ghost cats and cursed harps, spells that are supposed to go wrong and don't, a friendly sociopathic Death Eater... and Snape's very naughty, naughty library.

Occasional Table
Severus discovers that he is, in fact, an 'Inanimagus'--he can transfigure into things, instead of animals. Of course, life becomes interesting when he starts to transform into things Harry Potter can get his hands on...

Harry makes friends with one of nature's shy creatures. Just give it a chance. It's a fun story
