To free or not to free?

My first three months with Amazon's KDP are coming to an end and I have yet to use any of the 5 free days available to me. So I have been very indecisive whether to give this a go.
Part of me wants to scream and say - no way am I going to give my novel away for free. I have sweated blood and tears (and a bucket full of money) for this novel. Why should anybody be able to get it for free?
But then this other voice in my head pipes up and says - what can you lose? It's not like you're selling hundreds of books at the moment, are you?
In fact, the opposite is true. I am selling a few novels here and there, with long gaps in between sales, which can be quite disheartening.
So after hours spent online reading about the pros and cons of free give-aways, I have decided to give it a go. The best case scenario would be to get some new reviews out of this promotion and gain some new readers who will, in time, want to read my next book.
The worst case scenario would be (I can't even bear thinking about it), that nobody will know my book is available for free, and it won't be downloaded.
But I'm trying very hard to make sure that won't happen. So for two days starting from tomorrow, my book Teaching Tori will be available for free. Due to the timezone difference, this will actually only start at 9.00 pm on Tuesday if you are in New Zealand.
(And if you happen to download it, enjoy your read, and if you have a spare minute or two, please review it.)
