Review Detail of FrankJack in Harry Potter: Rubik's Cube of Heavens

The book isn’t half bad. Grammar is horrible, making the novel very confusing to read. The introduction is interesting, a little more in-depth explaination would be better. The only thing I dislike is cannon key elements being ignored, like Flitnick being labeled as half fairy. Magic wise is fine, I like the opens that is shown because of the MC’s past.
