SJ Griffin became a woman after successfully completing many years as a girl. After stints as an actor, a petrol station attendant, a copywriter, an editor, an amateur bike mechanic, a burger flipper, a playwright and riding an old fashioned bicycle in order to sell melting ice creams it became abundantly clear that the only thing she really wanted to do was write novels. So that's what she does. As a result she is far more pleasant to be around.
The Vanguard trilogy is the first stage of a long term strategy to remain pleasant to be around, for the general good of humanity. The Vanguard is out now, The Replacement will be published in June 2013 and the final part of the trilogy, The Perfectionist, will be published in December 2013.
After that? Well, you'll just have to wait and see.
If you're still curious you might like know that SJ tweets as @squintarium and has a blog called Adventures with The Vanguard which is about writing and publishing the trilogy.
