There’s a lot of snobbery in the air when someone mentions self-publishing. A lot of pursed lips and tut-tutting. It’s the last resort of a poor writer having been rejected by countless agents and publishers, isn’t it? .
Many think so, sadly.
I’ve read a few SP books and loads of “ordinary” books and have found errors in both. Funny, they are called spelling errors in SP books, but printing errors in books with a publishing house behind them.
The Pros and Cons of self-publishing can be found in the links highlighted. But, at all costs, make sure your book is the best it can be if you follow the SP route (by any route, really). Pay for a detailed edit/proof-read. Pay an artist for a good cover: these don’t have to be expensive. Shop around.
But be prepared to sell yourself; pimping on Twitter, Facebook etc. You’ll also make a lot of friends from all over the world, as I have found. I may not make my fortune from Eden but I’m sure going to have fun selling it!
