The Promise After (mike x eleven)

"Mike has never heard her, or anyone, for that matter, just wail with such utter despair that it sends a knife straight through his heart. His only coherent thought is that he has to find her, right now."

Mileven one-shot; takes place the night of 3x08 (The Battle of Starcourt). If you like angst or fluff, this may be right up your alley.
