Answer: When looking at the book Night by Elie Wiesel, the design on the cover seems to tell the reader that the book may be about a Jew from the holocaust, because of the Star of David. Books that are written about such topics commonly create a sense of dread/anxiety inside the reader. The mood that is reflected could be fearfulness. Simply by looking at the cover, these things can be inferred.
I hope this will be able to help :)
