While romance novels
tend to be on the «quick and easy» thin side of book length, other genres with titles like the Game of Thrones

ebook sales thanks to Baddeley's theory.
If you do not have a free
eBook of some kind (e.g., 1st book in a
series, short story, novella, sample chapters, etc.), your following messages
tend to be «buy my book» ads or senseless communication.
