Answer:
The chosen novel is the book "Inferno" written by Dan Brown.
Explanation:
In this book, The protagonist named Robert Langdon needs to embark on an adventure that requires a series of puzzles to be solved to prevent a public health problem from spreading across the planet, changing everything you know about economics, culture, society, among others. These enigmas are based on the poem written by Dante Alighieri: The Divine Comedy.
The adventure told in this book becomes exciting not only because of the mysteries surrounding the puzzles, but because there is a mystery around what this public health problem is, which is not revealed to the reader until the end of the book. Furthermore, we don't know who created the problem, or why it was created.
All these mysteries added to a narrative of frantic rhythm, involving great works of art and religious concepts like puzzles, make the revelation of the mysteries something extraordinary and extremely unpredictable.
