I apologize to Greg and the others here for sounding rude or harsh.
I went to the author's website, to Kobobooks and to the Kindle store at Amazon and I cannot find an e-book for sale from Greg. I don't see there is any Kobo book to promote -- which is the question that is posted.
For promoting an indie author in general, there is a wealth of stuff here on Mobileread, with Pholy offering a starting point.
PS - Sensualpoet is a he "nanny" not a she "nanny".
