I am writing my first novel but cannot decide if its best to write a trilogy or a single novel. The genre is mystery, new-age, suspense with a bit of fantasy. The foundational theme of the story allows for additional divergent stories to be told and developed so I'm thinking a novel with future tales in future but on the other hand, the single novel is a big story with many subplots that could be turned into an exciting trilogy, creating anticipation for readers. (The best example of this is probably how Great Expectations was originally written by Dickens). I know that there is no wrong or right answer but I am looking for a subjective answer as to the pros and cons of both. Thanks in advance.
I agree with all the above. I'd just about finished my first story, originally intended as a one-off, before I decided it might make a series.
Write your first novel. I'm sure that as you progress you will have many ideas for future novels. You may find you have enough ides for a trilogy or a longer series of novels. wh
I would say just write it and see what happens. By the time you've done a complete first draft & a bit of editing you're much more likely to know how you want to present it.
