Jo, Em and Joleen have never met. They interact only via the world wide web. Each must trust that they really are dealing with the other persons described in the bios. Not some crazy axe-wielding serial killer who uses writing forums as a hunting ground or harbours a fetish for those who feverishly edit and run multiple grammar checks.

Putting such fears to the backs of their minds, this writing trio set each other challenges and offer up ideas. Some of these collaborative efforts are featured in Casting Shadows. They share a passion for the dark things in life. These may be the dark things that lurk at the bottom of a lake, or buried deep inside a mind, just awaiting the opportunity to come screaming to the fore and commit bloody murder. The end of the world features prominently, as well as the end of sanity. These are all things that E.J. Tett, Jo Robertson and Joleen Kuyper ponder as they go about their daily lives looking for inspiration.
