Goodreads asked A.J. Vosse:

Where did you get the idea for your most recent book?

A.J. Vosse Ideas come from all around - past experiences often spark memories and those intertwined with fresh thoughts are the beginnings of new stories... then I just let the flow go and often the story resolves themselves.
I've learned not to force a story. If it doesn't work at first I will shelve it and then, sometimes weeks, months or even years later something will trigger the completion of a story... simple!
