  Summary

  The summer before his sixth year, Severus Snape finds himself without a safe place to stay until school resumes. Remembering an offer extended by Narcissa Black, the year she graduated from Hogwarts, he reluctantly makes his way to London to see if she can shelter him for a couple of months. Over the course of the summer, the two friends come to better understand each other, themselves, and the wizarding world that is being ripped apart just beyond their doorstep. And it may change everything. Timeline spans the summer before sixth year to the end of the war.
