Do KDP Select Free Days work?

At 4:30 p.m. this afternoon I took a look at where my debut Thriller VENGEANCE was on Amazon.

At that time I was # 2 in Private Investigators and #6 in the Crime Category.  I've since moved to #2 in both Categories and around 138 in the overall ranks for the Kindle Store Free books.

If you'd like to snatch a Free Copy of the VENGEANCE ebook you still have about 4 hours left.
