With the release of Harry Potter and the Cursed Child, I challenge you to either write a fan fic to improve the story OR follow one of the Alt worlds.
OK, Christmas is over, and I hope you all had a good one. Or whatever holiday you observe! My challenge is this, but I'm not doing well on writing it: Home Alone! You know the classic movie with Mac Culkin as Kevin - left behind by the family at Christmas. Picture the scene - the Weasley/Potter gang takes off, and leaves little Hugo, or Albus, or even little James behind. Mayhem ensues as someone tries to break in. Perhaps our hero even finds a wand and gets lucky - thus alering the MoM that a kid is using magic. Go for it!
