Beyond 84 Charing Cross Road (гет)

Devsgma and Darnedchild have combined their talents to tell you the story of what has happened to our favorite pair. It starts with a few letters from one extremely grouchy potions maker to the manager of a used book store. Canon through Deathy Hallows to the point of Severus Snape's supposed death at which point it becomes AU. This fic is a collaborative effort and was originally born from an aborted RP that never quite made it off the ground.
