I choose Harry Potter, books written by J.K. Rowling, because I think it is a gothic book. So I am going to talk about this wonderful saga.

Firstly, the story takes place in a castle wich is Poudlard and it look very gothic because it is gloomy and all around it there is a terrifying forest. Secondly, all of the students are wizards and witches, they are kind but some teachers looks very doubtful and anxious like the professor Rogue for example. Some parts of the castle are really misterious like "the secret room". Nobody really know where is this room and what kind of things are inside. There is some ghosts in Poudlard but most of them are kind and cool. There also are  "lively paints" because the people who are painted inside are moving and talking with students. Finally, there is Voldemort, the monster, the wicked character of the story who is extremely bad and angry with everybody but mostly with Harry Potter. So I think all of this details are making this story a gothic story.

This story is imaginary because there is some wizards and some witches, brooms are flying, there is some trolls, some ghosts and a lot of fantastic elements. They are making the story imaginary because everything seems perfectly normal.
