What I like about writing a stand alone novel is you're starting with a fresh world and fresh characters. Part of what I love about writing is that journey of discovery where it's all new to me as well.
What I love is the writing, it's not having written. I like the process of it.
In 'The Prophet' I really fell in love with those characters, there was an emotional connection there that I don't think I've had in a while. It made me think it would be nice to stick with the characters for a little bit and see what happens.
