Perfect for you if...
- You're fascinated by how major breakthroughs happen through a mix of luck, persistence, and the right people at the right time.
- You want to understand the real people behind the science, not just the sanitised textbook version of history.
- You enjoy narrative non-fiction that reads like a thriller because the stakes and human drama are genuinely high.
Maybe not for you if...
- You prefer books that stick to one hero's story rather than exploring the messy, complicated reality of how teams actually work.
- You want lightweight, feel-good inspiration rather than the complicated politics and credit-grabbing that come with scientific achievement.
- You're looking for a technical deep-dive into chemistry or pharmacology rather than a story about the people involved.
