Lucky Day, Chuck Tingle
Vera, a stats and probability professor gets caught up in what is literally a series of unfortunate events (A Low Probability Event) which changes the world. In what is essentially a post-apocalyptic story, she joins Agent Layne, of the Low Probability Event Commission (LPEC) to investigate the casino they suspect is behind it.
This story works on a scale both cosmic and personal. Like an anti-superhero story, LPEC is a nod at gross government overreach in the name of national security, saving the world, etc.
The first part of the book has some quite graphic depictions of bizarre deaths as a first person account of the Low Probability Event, which nearly put me off reading on. I'm glad I persevered to the end though.
