   Summary

   November 1981: Carmilla finds a dying infant on a doorstep, wrapped in a story the wizarding world will kill to control. His name is Harry Potter. She brings him to Laura, and together they choose him, fully aware of the price: England, safety, anonymity, and any hope of peace. They run to America and raise him as their son.

   This is the story of two vampire mothers and the mortal child they claimed, in a life where forever makes love both harder and more absolute.
