A Wish for the Damned (гет)

Sometimes, the end isn't the end, and Death is just a holding place in need of some colour. Magic protected her son, and it gave her a wish in exchange for her sacrifice that saved the world. She doesn't know what to wish for until she realises there's only one thing worth that wish... if only that 'thing' wasn't quite so uncooperative with her attempts to make the wish come true. But then, nothing ever came easy for her and Severus, so it's only fair that coming back to life isn't either.
