Maybe you'd have to be me to find this exciting. But the horse race is on at amazon.com between my two most recent, rather substantially different, publications:
1) Decoding the Corporate Tax, currently ranked # 426,062 in Books, and
2) Getting It, currently ranked # 445,077, but more likely (as a very recent publication) still to be headed up.
If I can write 'em both, I don't see why you can't read 'em both.
UPDATE: Getting It has broken into the top 200,000. Can't let this become obsessive, however.
FURTHER UPDATE: #54,000, but up and down a lot. Okay, I'll stop.
