Titles are like the first shot of adrenaline in a sci-fi story—they need to hook you instantly. I always look for something that teases the core conflict or theme without giving too much away. Take 'Neuromancer'—it sounds sleek, dangerous, and hints at tech without overexplaining. I also love titles that play with juxtaposition, like 'The Three-Body Problem,' where something scientific collides with poetic weight.
Another trick is mining mythology or history for resonant phrases. 'Hyperion' borrows from Keats but feels futuristic, while 'Snow Crash' mashes up digital slang with apocalyptic vibes. If I’m stuck, I brainstorm single words that embody the story’s soul—'Exhalation,' 'Annihilation'—then expand. The best titles linger like a hum in your skull.
