Ball Lightning is an early book of Cixin Liu, the Three-Body Problem trilogy author. While not as good as its trilogy, the book was interesting to read because of its theme: Science.
The protagonists try to understand the ball lightning (a real phenomenon). The whole book is structured around their experiments, their thoughts, and failures. The end of the book goes a bit far, and is clearly “science-fiction”, but still in a “hard”, plausible way. This won’t surprise those who read the trilogy.
