This story is a Harry Potter crossover with Jurassic Park. It’s actually a little confusing if you haven’t seen the Jurassic Park movie or read the book in awhile because the character names are used but the descriptions aren’t very good because the author assumes that you know what they are supposed to look like. That is the only bad thing I can think of. Other than that the story is fantastic! It is of course a rewrite of the Jurassic Park storyline where Harry drops in and fixes it either on purpose or by accident.
