Anyone on Pottermore? It’s an interactive site about the Harry Potter books. You follow the story chapter by chapter, picking up items (Galleons, Chocolate Frog cards, potions ingredients, etc.) so you can play along. You get to buy supplies in Diagon Alley and get sorted into a House.
You can have wizard duels and brew potions. If you win the duels and brew the potions correctly, you win points for your House.
Right now, all the way through Sorcerer’s Stone is available.
It’s the nerd/child in me, but it’s fun.
There are also interesting facts about the characters and certain aspects of the stories that weren’t in the books. For instance, there is a whole background story on McGonagall and her family. All stuff that Rowling created but never put in the books. When you find certain objects, you unlock stuff to read from Rowling.
If you’re on it, look for me: AurorDust10933.
