The Winter Queen has a mission for the Winter Lady and Winter Knight, and they are going to make quite the impact on Harry Potter, on the Ministry, and at Hogwarts. After Cold Days in Dresden Files. Beginning of OotP for the HP Books. Slight AU before and major split during the course of the story. HP/HG and possible HD/MC. Please judge the story on the story and not the summary.

When Harry Dresden awoke that morning, a distant warning bell was echoing in his head. The kind of thing that usually alerts a Wizard that bad things are lurking in the day ahead. How bad? Try an elder god knocking on his front door, the timeline recently fractured and barely patched back together again, and the threat of the Outer Gates crumbling. Can he find a way to fix it all?

After the Battle of Hogwarts Harry meets a powerful magical practitioner named Ivy, who asks the young hero for a small favor. She wants him to be the father of her children.

Sequel to Allies. Sam and Dean return to Chicago in search of a way to defeat Lucifer, but are in for more than they bargained for when Fallen Angels from Harry Dresden's rogues gallery get involved. Post Supernatural season 4 and Small Favor
