Laura Boone recently started a literary agency in Johannesburg, and is accepting submissions, provided you follow the submission guidelines.
The agency was founded at the beginning of 2007 as a special interest division within the Laura Boon Communications Group to address a need in the market place for a South African-based literary agent to represent SA authors both locally and internationally.
Laura has more than 10 years experience in the book trade. She worked for Exclusive Books, at both the Sandton City and Hyde Park branches. She also worked in the marketing department of publisher Random House and has worked as a book publicist for the last six years.
