Teenagers are extremely smart, and if they think for even a second that an author is 'writing down' to them, or mimicking their voice poorly, or condescending to them in any way, they will throw the book across the room.
The undiscovered places that are interesting to me are these places that contain bits of our disappearing history, like a ghost town.
Just the textures of things are really important to me as I'm writing; I think atmospherics and visuals can have such emotional impact if you can harness the thematic thread between how scenes look and how your characters feel. I like to tug on that thread.
I think my background in film taught me that a great book adaptation is not always slavishly faithful to the source material.
'Library of Souls' is longer than 'Hollow City' by a considerable margin, but this time I was on the right track from the beginning, so I never had to start over. It took about 15 months, all told.
The end of 'Hollow City' left the peculiar children in a very precarious spot, and that's just where 'Library of Souls' begins.
