There are a few contests currently open to aspiring romance writers in South Africa:
If you have a completed single title novel you might consider Penguin's contest for aspiring African authors. For more information, check out http://www.penguinbooks.co.za/african-winners/index.php.
For category romance writers, Harlequin is running another Presents contest (Modern & Modern Heat to us here in SA). All you need to enter is a synopsis and first chapter - but as Amanda Holly can attest, it's probably a good idea to have written a little more than that! Winners of the last two contests have already sold their completed manuscripts to Harlequin, but even if you aren't confident of winning, I highly recommend you enter. Every entrant is guaranteed feedback and I know several people who've had full manuscripts requested based on their entries. (Isn't it time you submitted yours, Mandy?) Details are available on http://www.iheartpresents.com/2009/07/official-rules-for-the-harlequin-presents-writing-competition-2009/.
Finally, Essentials magazine is running another Voice of Africa short story contest in conjunction with Mills&Boon. Pick up the August issue of Essentials, or visit their website at http://www.essentials.co.za/index.php?p[IGcms_nodes][IGcms_nodesUID]=da425e83de610e013f2f16d3fdbfdca3. The prizes are absolutely awesome!
So get writing, and please leave a comment to let us know if you plan to enter any of these. Good luck to all entrants!
