Quit: How Not to Be Wrong: The Power of Mathematical Thinking by Jordan Ellenberg, 2014, from Overdrive.com
I took a one day class on the Wisconsin state budget process. The instructor mentioned this book by a UW Math guy in reference to sketchy and manipulated numbers used in state budgets.
I was enjoying the book, and it is interesting, but I need to see the numbers on the page. I'll get a print copy. The 12-year-old might like this one.
Ellenberg narrates the book and does a good job.
1. There is a comment by Ellenberg that most people will agree with. When someone with a hare-brained scheme compares themselves to famous thinkers, "People thought Galileo and Einstein were wrong," you can safely figure the speaker is a nut.
