Lay your head to sleep

Harry Potter was cursed. Severus Snape had thought Lily's sacrifice saved him from that fate...but when Hagrid is unable to deliver Harry's Hogwarts letter through the wall of thorns, Severus is sent instead. There he finds a child surrounded by magic and the flock of sleeping owls turns out to be the least of his troubles. Retold Fairy-tale.(Sort of Severitus) (Pre-Slash: Snarry)
