'Der Roman' means 'novel' (a book). It is a false friend with the English word 'Roman', which refers to ancient Rome.
Für meinen Urlaub habe ich mir drei dicke Romane gekauft.
I bought three thick novels for my vacation.
Other useful words are derived from 'Roman' (novel), such as 'der Romanautor' (a person who writes novels) or 'die Romanfigur' (a character in a novel).
Die Hauptfigur in diesem Roman ist sehr interessant.
The main character in this novel is very interesting.
'Roman' (novel) is often combined with verbs like 'lesen' (to read), 'schreiben' (to write), or 'veröffentlichen' (to publish). You can also combine it with genres, e.g. 'Kriminalroman' (crime novel), 'Liebesroman' (romance novel), or 'historischer Roman' (historical novel).
Sie hat gerade ihren ersten Kriminalroman veröffentlicht.
She has just published her first crime novel.
In everyday language, 'Roman' (novel/long story) is often used colloquially for a very long and complicated story. It is usually used to express impatience.
Ich habe nur nach der Uhrzeit gefragt und er hat mir einen ganzen Roman erzählt.
I only asked what time it was, and he told me a whole long story.
story / history
Geschichte is a neutral term for a narrative. Roman can also be used colloquially to mean an account, but in that use it emphasizes, critically or humorously, that the account is excessively long and complicated. Geschichte fits a normal narrative, while Roman fits an account that is far too long.

Sie erzählte uns einen ganzen Roman über ihre Reise.
She told us a whole novel about her trip.
Sie erzählte uns die Geschichte ihrer Reise.
She told us the story of her trip.
