1st Novel
There will be mistakes since it's the first. The idea of writing this occured to me when I saw a reel of the boggart scene where Harry sees a death Eater. I thought of Harry seeing a evil himself with boold in his hands smiling Coldplay at him . This caused me to write this to make this idea a reality
Hope y'all support me
