Cripple Me by krosi starstarstarstarstar [Reviews - 178]
Severus Snape hates Harry Potter. Nothing will ever change that. Nothing. Not even the boy’s sudden intrusion in his life. Or that cheeky smile. Or that all too innocent look.

An eventual Snape adopts Harry story. Beginning in Harry’s first year.
