OMG. It's the classic One Big Happy Snape-Potter-Dumbledore Family fic! I adore these in a slightly twisted way. Half the characters die, and the other half live in an ever-evolving soap opera. With curtains. :D Evil!Hermione is so reliably evil (but always defeated), Harry and Snape suffer beautifully!!! It's not complete without gay Dray, and a repentant Ron, and of course, there are unbeatably cute, clever, smart, yet perfectly mannered adorable twin children who will be Slytherins (or Ravenclaws) - and now, in bunny suits! SQUEE. You hit all the notes perfectly!
I love Minerva & Snape's animagus forms "playing" together. Snape as a small black fox is so cute. *pets him* ...er, *carefully* pets him.
There's nothing like AU OOC Snarry schmoop to reaffirm our love for them. Well done, mystery author!
