When an AI can generate a novel, write code, or diagnose symptoms, the skill that separates you from the noise is the quality of your prompts. Mastering Prompt Engineering is not about talking to robots — it's about learning the precise language of collaboration with intelligent systems. Whether you're a marketer, teacher, developer, or executive, this book gives you a repeatable framework to get consistent, useful outputs while avoiding common pitfalls like hallucinations and bias. You'll discover how to structure prompts for clarity, inject context without confusion, and adapt your technique as models evolve. Each chapter builds from foundational principles to advanced strategies for multi-step reasoning, persona crafting, and iterative refinement. Sophia Lund Alvarez draws on real-world examples and hands-on exercises to show you how to stay irreplaceable when machines can think. The result: you don't just use AI — you direct it.
