Sure. 'Literary work' can be used instead. A novel or a book is a type of literary work which is created through the written word and often has some artistic or creative value.
'Opus' can also be considered. It is a more formal or perhaps a bit old - fashioned term. It can be used to refer to a significant work such as a great novel or an important book. For example, a writer's magnum opus would be their greatest or most important work, which could be a novel or a book.
For book, there's 'libretto' which is mainly for the text of an opera but still a form of book. Another one is 'ledger' which is more like a record - keeping book. For novel, 'saga' is a great alternative as it implies a long and involved story like a novel, and 'epic' can also be used to describe a grand and long novel - like story.
Storytelling can also be called 'recounting'.
Central figure. Just like in 'Romeo and Juliet', Romeo and Juliet are the central figures. They are the ones the story is mainly about, and their relationship and the events around it form the core of the play.
Naturalistic fiction. It is similar to realistic fiction as it presents a view of life that is based on the idea that nature and the environment play a big role in shaping human character and behavior. For instance, works that show how a person's upbringing in a rural or urban setting affects their life choices can be considered naturalistic and also realistic fiction.
Sagas. Sagas are long, involved stories, often with a historical or cultural background. They usually tell the story of a family or a group over a long period of time. For example, the Icelandic sagas which are a collection of long stories about the early settlers in Iceland, their lives, adventures, and family feuds.
Autobiographies. These are self - written accounts of a person's life, which are essentially life stories written by the person themselves.
Family chronicle. It's like a record or account of family events over time.
During the whole novel. It is a simple and easy - to - understand alternative. Just like when you talk about an event that happens continuously during the whole novel.
