The Curious Case of the Self-Loathing Lit-Fic Book Trailer. I have watched several trailers and for the most part they do not make me want to write the book. They either have been really lame or dry.

My best guess is that they are school assignments designed to help teachers, storytellers, librarians learn to do book talks.

WRAP UP:
I am really glad to have completed this project. Completing it took more time than I thought it would. Being reminded that I had a goodreads account was good and following Daily Beast Books was also a plus.
