I don't usually watch book trailers because most of them are just badly done, but this one for Barbara Sheridan's Falling Through Glass is quite impressive and looks very professional. However, once I learned the story behind the trailer, I was astounded:

1. The book trailer was made by Barbara Sheridan's teenage daughter.
2. The budget for the trailer was $0.00, and therefore, Barbara's daughter was severely limited in what she could use.
3. All the images in the trailers are free stock photos or pictures Barbara's daughter took.

Take a look. It's fantastic. I wonder what Barbara's daughter can do with more contents.
