Planning where the book will be found.

The key element of the trailer will be the notebook, so I've been brainstorming how and where it will be found.

I still need to think about where it'll be discovered, but the idea of a paper trail leading the girl to the book might be a consideration.

I've also considered the idea that there maybe some form of warning towards Carla before she picks up the book. For example, if the book was stranded in the middle of a pelican crossing, the red man will light up providing a signal not to cross, but Carla will still take the chance to take the book though she's been warned.
