Check out my blog @

I am a black male fiction writer, many times published, but it has been a struggle for every inch mainly due to this perception that 'black men dont read/read fiction.'
I, like you, read Grisham, King but also Walter Mosley & Donald Goines. My style is a mixture of my influences.
Hope you enjoy the stories i've posted on the blog and dont lose hope-there are still some writers out there channeling the influences you named.
