The world has to be delivered without stopping the story, and the failure — an exposition chapter about how the drive works — is so common it has a name.

- Worldbuilding delivered through action, not explanation
- Proper nouns rationed — two in the blurb, few in chapter one
- Internal consistency of rules across the whole book
- Whether the idea is doing work the plot should

What's different about a science fiction novel
The world has to be delivered without stopping the story, and the failure — an exposition chapter about how the drive works — is so common it has a name. Decide how hard the science is and hold it: a book that is rigorous for six chapters and hand-waves in the seventh loses the readers who came for the rigour.
The shape underneath it
Something has to change in every chapter. Remove one: do the ones after it still work?
Typical length: 80,000–100,000 words
Who reads it: Readers of a specific sub-genre with 200 comparable books read and precise expectations about where the floor usually is.
Where a novel most often goes wrong: A middle act holding position rather than escalating. It is where most novels are abandoned.
Test the structure before you write into it
The cheapest intervention available in any category: an outline critique costs £150–£400 from a human editor and catches in a fortnight what a finished draft takes six months to reveal.
For a science fiction novel specifically, the checks above are the ones worth running against your plan — and running them at outline stage is the difference between a structural fix and a rewrite.
What it costs to finish
British rates for a novel, dated 9 September 2026 and sourced to CIEP suggested minimum rates effective 1 March 2026 and Reedsy's published marketplace averages. Every row on the cost pages carries a confidence flag: sourced, derived or estimated.
What Your Book Pro does here
Your Book Pro is a British book-writing platform. You bring a book — an idea, a folder of notes, half a draft, or a finished manuscript written somewhere else — and it gives you the editorial process a publisher would run: a plan, structured feedback, a simulated beta read, a line edit, a proofread, a cover, a blurb and a print-ready file. You can type it, upload it or speak it. The tools sit in one place and work on the same manuscript, so the feedback compounds instead of arriving as twelve disconnected opinions.
For a science fiction novel the useful order is: the Book Coach first if you do not yet know what the book is — free at yourbook.pro/book-coach with no account. Then Plan Feedback to test the structure against what this form actually requires, before you write into it. Then Detailed Editorial Feedback on the draft, Beta Reader for the reader's-eye check, the Editing Suite for the passes in order, and Proofread last.
Plus lets you upload a manuscript you wrote anywhere, run whichever tool you actually need, and export it again. No subscription to start, 1,000 welcome credits that never expire, and a plain export of your own words is free forever.
And the honest limits are on every tool page: real readers in your actual audience, a designer who knows your shelf, and a solicitor where a book names living people are all real purchases at real prices.
Writing a fantasy fiction
Magic needs rules and, more importantly, costs — a system with no price attached removes tension from every scene it touches. The other constant is the sub-genre question: grimdark, cosy, epic and romantasy have almost nothing in common in tone, length or cover, and readers scan for the signals before page one.

Writing a mystery crime fiction
Crime readers have read two hundred of these and know exactly where the floor usually is, which makes structure less forgiving than in any other fiction. The clues must be fair and present; the reveal must be inevitable in hindsight and surprising at the time; and the sub-genre — cosy, procedural, psychological, noir — sets the tone, the violence level and the cover.

Writing a romance fiction
Romance has genuine structural requirements readers treat as a contract: the central relationship is the plot, and the ending is happy — HEA or HFN. Breaking that is not innovation, it is a different genre with the wrong cover. Heat level and trope signalling need to be explicit in the blurb, because readers select on both.

Writing a historical fiction
Two failure modes pull against each other: research that never reaches the page, and research that reaches all of it. The reader wants to believe the world, not to be taught it. Anachronism in language is the specific technical problem — not just vocabulary but idiom, sentence rhythm and the concepts a character could plausibly hold.

Writing a horror fiction
Horror is a pacing problem before it is anything else: dread accumulates and is spent, and a book that is frightening for three chapters and then exhausting has spent it wrong. The sub-genre decision — quiet, supernatural, body, folk — governs how much is shown and when.

Writing a literary fiction
Literary fiction is where the sentences are the point, which raises the bar on line-level work and lowers the tolerance for structural slack. It is also the category most often used to excuse a book with no engine — and 'nothing happens' is a real problem even when the prose is good.

Writing a young adult fiction
YA is defined by the protagonist's age and the immediacy of the voice, not by simplified content — it handles difficult material directly and its readers are unforgiving of condescension. The adult-solving-the-problem failure is fatal here in a way it is not elsewhere.

- Should I outline first?
- For this form, yes — an outline critique costs £150–£400 and catches in a fortnight what a finished draft takes months to reveal. It is the cheapest editorial intervention there is.
- Do I have to write it here?
- No. Upload a manuscript written anywhere, run what you need, and export it again. A plain export of your own words is free forever.
