One great book for this could be 'The Martian' by Andy Weir. It's about an astronaut stranded on Mars, which is another planet, and he has to survive in what could be seen as an end - of - world situation for him. The story is full of scientific details and the protagonist's struggle for survival.
The Orc in 'The Lord of the Rings' series can be seen as a type of disfigured monster. They have a rough and ugly appearance, with large fangs and a generally menacing look.
It could be the main character themselves. Sometimes, in a psychological thriller, the character discovers that they are the source of all the problems, and in a way, they are the monster.
Denouement. It is a French term that has been adopted into English to specifically mean the final part of a story where all the loose ends are tied up, secrets are revealed, and the story reaches its final resolution. It often comes after the climax of the story and is a more literary or sophisticated way of referring to the end of a story.
Well, it could be a symbol of fear or the final challenge in the story. Maybe it represents the unknown that the characters have been dreading all along.
The significance could be to create suspense. It makes the reader curious about what the monster actually is, whether it's a literal monster or a metaphor for something like a big problem or a character's inner fear.
I'm not sure as you haven't told me the specific story. But it could be various actors or characters depending on the nature of the story. For example, if it's a horror story, it might be a well - known horror actor like Robert Englund if it's a Freddy Krueger - like monster.
I'm not sure who the specific author of a work named 'the monster at the end of the story' is without more context. There could be many works with this title or a similar concept, and different authors might have created them.
