A Grammar of Scent
Ines Okafor is the only licensed translator for the Vell, who speak by changing the smell of the air, and she needs the contract renewed so her daughter can stay in the colony school.

Science Fiction: what makes the plot work
Science Fiction explores the possibilities of advanced science, technology, and space exploration, often tackling complex ethical and philosophical questions.
Build the plot from one question
Strong science fiction often grows from a single question asked seriously. In The Left Hand of Darkness, Ursula K. Le Guin asks what a society would look like if its people had no fixed sex, then sends an envoy who keeps misreading it. Write your question in one line, then ask who gains, who loses and who doesn't understand.
Let the science make the problem
In Andy Weir's The Martian, the physics that strands Mark Watney is the same physics he uses to survive, from growing potatoes to making water. When the science creates obstacles and also offers the way out, the plot feels earned. Readers distrust a solution that arrives from nowhere.
Make first contact a language problem
Aliens who speak perfect English waste the best material. Ted Chiang's novella "Story of Your Life" follows a linguist learning an alien written language, and the way it changes her sense of time becomes the plot. Whatever your aliens are, decide what humans will get wrong about them first.
Keep the human cost in front
Kazuo Ishiguro's Never Let Me Go barely explains the science of its cloned students, yet it is unmistakably science fiction because every scene shows what the technology costs them. You can leave mechanisms vague if the consequences are specific. Readers remember the person, not the lab.

Questions about Science Fiction plots
What's the difference between hard and soft science fiction?
Hard science fiction keeps close to known physics, biology and engineering, and the accuracy is part of the appeal. Soft science fiction focuses on societies, psychology or politics and treats the science more loosely. Most books sit somewhere between, so decide which matters more to your readers: the problem-solving or the people.
How long should a science fiction novel be?
Many adult science fiction debuts land roughly between 90,000 and 120,000 words. Space opera and series openers often run toward the upper end, while near-future and literary science fiction can be shorter. If you are well past 120,000 words for a debut, look hard at worldbuilding scenes that don't move the plot.
How do I explain the science without an info-dump?
Give the explanation only when a character needs it to make a decision, and break it across scenes. Arguments, mistakes and failed experiments carry information better than lectures. If two experts would never say it to each other, find another way for the reader to learn it.
