David Gaughran is one of the more instructive indie-publishing gurus out there. I recently read his STRANGERS TO SUPERFANS and found it to be as practical a guidebook as it was inspiring a read. I will definitely check out the other three books in the series.
As an example of how in-depth David Gaughran covers a subject, allow me to direct you to his blog entry (an excerpt from another of his books) wherein he covers the subject of amazon categories.
For a sample of my writing, pick up a FREE e-book copy of the first installment in my space opera, The Holy Terran Empire. I published it wide and thus the e-book is available through most retailers.
