Prompt: 16: Wartime!fic. The Battle of Hogwarts was a failure. Voldemort is still alive, and survivors take refuge in Hogwarts, Grimmauld Place, etc. Severus is there convalescing (much to his dismay), and Harry soon starts looking to him for help with strategy. Feelings develop.
Summary: Severus Snape should be dead. Instead, he wakes up after the Battle of Hogwarts to find himself quarantined in a house full of Gryffindors, waiting for Harry bloody Potter to save the world…again. And Severus must be going crazy because he can’t stop thinking about Potter. (Or, where Harry needs a distraction, and Severus doesn’t refuse.)
A/N: Thank you to the mods for their patience and extensions. Title credit goes to Torino after providing much needed and very last minute assistance and inspiration! This story takes place in the months following the Battle of Hogwarts; Harry turns 18 shortly after it begins.
