Barnes & Noble, Kobo, and Payhip (PDF) in addition to Amazon. If you are in Canada, this is good news!
Kobo and Barnes & Noble have a wider distribution than Kindle, so this book will be more available to people living abroad. Kobo has minimum price requirements that made it necessary to raise the price by one dollar (US). But, it's still very affordable at $3.99. (Anyone who can't afford the book at that price can simply email me, and I will send a free PDF file.)
For those who would rather have a PDF file delivered directly to their computer, a PDF file of book can be ordered from Payhip.
If you already have a copy of the book, and have reviewed it, please put a copy of your review on Barnes & Noble and Goodreads. Feel free to rate it on Kobo, and to tweet it on Payhip.
Thank you !!
