Once I've had everything

AU! Snape's life after graduating. What can turn the most loyal Death Eater away from his Master? Why did he betray Voldemort and became a spy for Dumbledore? What happened to his family? Ignores HBP and DH. Written in 2004. Translation. If you liked it, you should read the novel it belongs to. It's called The Boy With The Piercing Blue Eyes (on my profile). Story up on LiveJournal
