Cycle. A cycle of novels is also a term that can be used instead of series of novels. Think of something like the 'Wheel of Time' cycle, which consists of many books in a sequence.
Saga. For example, 'The Lord of the Rings' can be considered a saga, which is just another way to refer to a series of novels.
Sequence. This word can be used to describe a series of novels as well. For instance, a sequence of detective novels where each book is related to the others in terms of plot, characters or the overall mystery that is being gradually revealed throughout the sequence.
Tales. Tales can be short or long, and novels are a type of long tale. Tales often have elements of fantasy, adventure, or moral lessons, which are also common in novels. For instance, many classic novels are full of tales of love, heroism, and the struggle between good and evil.
Library (in a more metaphorical sense). While a library is a physical place where novels are stored, it can also be used to represent a collection of novels. For instance, we can say someone has a personal library of novels, meaning they have a collection of novels that they own or have gathered over time.
Stories. Novels are a form of story -telling. They contain a sequence of events, characters, and a plot, which are the basic elements of a story.
Well, 'noticed' is another word for'seen'. When it comes to 'novel', 'original' is a great alternative. The word'seen' implies the act of visually perceiving something, and 'noticed' has a similar meaning but might imply a bit more of an awareness. 'Novel' means new and different, and 'original' also gives the sense of being new and not a copy.
Trilogy. For example, 'The Lord of the Rings' is a well - known trilogy.
For'seen' in writing, 'viewed' could be used. For 'novel' in writing, 'unprecedented' is a good alternative.
Book. A novel is a type of book, so 'book' can be used as another word in a general sense.
Narrative. A novel is a long narrative work. It tells a story, and 'narrative' emphasizes the storytelling aspect, so it can be another word for novel.
