I've been chatting a fair bit this week to a nice gentleman called Mark Newton, who is the assistant editor at new-ish genre publisher Solaris.
Mark is currently writing a series of articles about how to get published, with advice on what common pitfalls to avoid and how to make your work more appealing to publishers (and agents).
The real value of these articles is the fact that Mark is an 'insider' as it were, who has valuable knowledge of the industry. This, I feel, lends some real weight to his advice (in other words, he knows what he's talking about). Mark also happens to be an author in his own right, having signed a deal that will see his fantasy novel The Nights of Villjamur published by Macmillan.
