My Novel Free on Kindle Friday and Saturday

It seems weird to give away a book that I've spent hours writing and revising and now marketing, but that's just what is happening today and tomorrow. My novel, The Summer of France, is free on Kindle.
I have to honestly say that I don't understand how it works, but somehow, giving away my novel increases my chances of being seen by buyers after the giveaway is over.
I did an ebook giveaway in February and the number of sales have doubled in March. So here I am again, offering my book for free. I'd love to get a double double in April (That's basketball talk in honor of March madness.)
If you don't have a Kindle, which I don't, other options abound. You can go to the link and there's a place to click on "Get your kindle here free" and what that means is the Kindle reader is free to download to  your computer. So you might have to download the Kindle reader before downloading my book.
I have a Kindle reader on my iPhone and download books there.
If you haven't read my book, I hope you'll take this free chance to try it and then tell me what you think.
Even if you don't plan to read it, I'd appreciate it if you'd download it anyway just to help my numbers.
Here's the link to The Summer of France -- free Friday and Saturday.
Update: Thanks for your support everyone. How can I convey my excitement as I tell you this?
Squeeeee!!!
In the category of France, I'm #1 in the UK and #2 in the US. In the category of Family Life, my novel is #10.
So exciting to see my book move up the list.
Another update: Okay, now I'm #1 in the UK and the US in the category of France and #6 in the category of Family Life.
Double squeeee. Here's the screenshot to prove it. Click on it if you need the print bigger!
