A Helping Hand
I got an email from Amazon telling me that customers bought hundreds of thousands of kindle ereaders on Black Friday and I was thinking 'if only there was something in it for me' and then yesterday I had my best day on Kindle ever, surpassed by sales today!
I'd like to celebrate by giving something back to others. If there is someone out there who is struggling with writing a blurb and needs a hand, get in touch by sending me a private message.
