Answers to frequently asked questions about alien books and how to write them

1. How can I create a believable alien species in my story?

To create a believable alien species, focus on consistency in biology, culture, and technology.

Consider evolutionary pressures that might shape the species physically and socially. Their technology should reflect their needs and capabilities.

To make them compelling, give them unique traits but ensure they have logical reasons to exist in the framework you’ve built.

2. What are some common tropes in alien-themed literature that I should be aware of?

Common tropes include the wise and ancient alien race, hostile invasions, abductions, and the “humanoid alien” with slightly modified human features.

While these tropes aren’t inherently bad, be mindful of how they can become clichés.

Offering a fresh twist or deeper examination can make your work stand out.

3. How do I handle the science in my science fiction book about aliens?

The level of scientific detail depends on your story’s needs and target audience.

Hard science fiction benefits from accurate scientific theories and terminology, while softer science fiction may prioritize narrative over scientific rigor.

In either case, ensure that the science serves the story and adds depth rather than confusing the reader.

4. How can I incorporate themes of cultural exchange or conflict between humans and aliens?

To explore cultural exchange or conflict, develop a well-defined social structure, ethics, and belief systems for both the human and alien societies in your story.

Conflicts or synergies should arise organically from these differences or similarities.

Readers find stories compelling when cultural interactions are complex and not reduced to mere “good versus evil” dynamics.

5. What’s the key to maintaining tension and pacing in an alien-themed thriller or mystery?

Maintaining tension in an alien-themed thriller involves raising stakes that are both personal and global.

Pacing can be controlled through cliffhangers, revelations, and action scenes.

Mixing intimate human drama with the larger-than-life alien elements can create a layered tension that keeps readers invested in the story.
