Here are a few all-genre book events I know of.
The North Carolina Writers Network has two conferences annually, one in Greensboro each April and a fall conference that rotates between Charlotte, Wilmington, Asheville and Raleigh-Durham. http://www.ncwriters.org/
And I had a great time at the Dahlonega Literary Festival. March 25-26, 2017. https://literaryfestival.org/
And check out the Atlanta Writers Club conference, May 12-13 at https://atlantawritersconference.com/about/
