A good read
I enjoyed the story for the most part. Reading a Harry Potter story written from a 1st person perspective was a bit weird as it didn't match the style of the official books. The writing style and punctuation was average as it didn't match the recommended style for novels but this was only a minor distraction from the plot. The grammar was actually fairly good.
Read the story now
I enjoyed the plot through most of the story and the author had a fairly good understanding of the Harry Potter world. The characters seemed believable and were true to the original stories.
I can't really comment on the ending as I do not want to stop people from reading the story, but I will just say it wasn't what I was expecting.
