Setting aside things like Harry Potter, The Hunger Games, or the Nicholas Sparks canon as trying merely to reiterate as much
plot event as possible in a moving image form, is the job of the adapter to be faithful to the original text?
Figure out what keywords (locations, genre, theme, activities,
plot events) would appeal to your target readers, then use the images and cover text to say
as much
as possible about the novel, so that the right readers will be instantly attracted to your book.
