Wow, just wow!! I absolutely loved this and can't understand why I missed it when it was first posted. Mind you there are a few stories that I haven't read yet.
It was a perfect lazy Sunday read. I love, love, love deaged Severus and the way that Harry befriended and then seduced him. I loved the way that he was still recognisably Snape and rejected anyone that wasn't Harry (apart from the reluctant inclusion of Hermione.) His struggle with his sexuality was so poignant and I also really liked the way that he wasn't bullied. The Gryffindors found him standoffish but seemed to accomodate him well enough.
Only complaint? I would so like to see more of this verse.
