Inferno, by Dan Brown. Unabridged audio.
I have read all of Dan Brown's novels, and have liked them to varying degrees. This one moved (mostly) away from the religious world to the art world, but other than that, this book was similar to his prior novels. If that works for you, than you ought to enjoy this one, as well.
The epic poem The Inferno is the jumping off point for this novel, as are famous works of art inspired by the work. From there, the conspiracy runs to a cabal of trans-humanists who want to dramatically cut the world population. And they have an interesting method about how to do that.
There is a lot of problem-solving, puzzles, and a whole range of such brain-teasers that only Robert Langdon can solve. There are a lot of coincidences and moments of good fortune that occur, a few more than I would prefer.
One of the strengths of the novel is the pacing. The novel takes place over a very short period of time, and that certainly helps the reading experience. The fast-moving nature of the book helped me overlook some of the book's shortcomings.
