Below is a complete science fiction query letter written by our editorial team to model what works in this genre — followed by line-by-line annotations and science fiction-specific querying norms. The book and author are invented; the techniques are what we coach in real reviews. For the underlying structure, start with the complete query letter guide.
The example letter
Dear Dr. Imani,
Because you represent character-forward science fiction and have asked for "stories where the ship is a society, not a setting," I hope LULLABIES FOR A DYING SHIP will resonate.
LULLABIES FOR A DYING SHIP is a 98,000-word science fiction novel for readers of Becky Chambers and Emily St. John Mandel.
Hospice nurse Oba Reyes has the strangest job on the generation ship Perennial: she midwifes good deaths in a society built to outlive everyone aboard. Four generations from launch, three from arrival, the ship's culture runs on one promise — your great-grandchildren will breathe real air. Then a dying engineer gives Oba his deathbed confession: the Perennial changed course forty years ago. There is no destination star. The ship has been circling back toward Earth for longer than Oba has been alive, and the captains' line has buried it for two generations.
Oba is not a mutineer. She's the person who holds hands in the dark. But her patients' final words keep assembling into the same buried map, and the ship's young — who were promised a planet — have started a quiet religion around the lie. When the captain offers Oba a choice — keep the secret and let the ship die believing, or tell the truth and watch a sealed world tear itself apart with nowhere to go — she has to decide what hospice means when the patient is a civilization.
I've worked eleven years in palliative care, and this book asks what my field taught me: whether hope must be true to be worth something. LULLABIES is my debut, complete at 98,000 words.
Thank you for your consideration.
Sincerely,
Marisol Teague

Why this query works
- The conceptual hook is a job we recognize in a place we don't — hospice on a generation ship. SF queries work when the human angle leads and the hardware follows.
- The reveal lands in the query, not the twist: "there is no destination" is the premise, freeing the description to pitch the real story — what to do about it.
- The thematic question is dramatized, not announced. "What hospice means when the patient is a civilization" earns the theme through situation.
- Comps signal lane precisely: Chambers + Mandel says literary-adjacent, character-driven, warm — not military SF, not hard SF. Agents route queries by these signals.
Querying science fiction: genre-specific advice
- Lead with people; let the technology be load-bearing but off-page in the query.
- Name your lane via comps (space opera, climate fiction, first contact, literary SF) — SF agents' wishlists are lane-specific.
- One novum pitched clearly beats three pitched vaguely.
- Adult SF runs 90–110k; pitching 140k as a debut invites an auto-pass regardless of premise.
Frequently asked questions
How long should a science fiction novel be to query agents?
90,000–110,000 words for adult science fiction. Pitching a 140,000-word debut invites an auto-pass regardless of premise.
How much technology should I explain in an SF query?
Lead with people and let the technology stay load-bearing but off-page. One novum pitched clearly beats three pitched vaguely.
What comp titles should I use in a science fiction query?
Use comps to name your lane — space opera, climate fiction, first contact, or literary SF — because SF agents' wishlists are lane-specific.
