The Millions recently ran a piece entitled Judging Books by Their Covers 2013: U.S. Vs. U.K. that compares book covers in the United States to their literary counterparts in the United Kingdom.
It’s an interesting look at the different interpretations of a novel. My reactions to the books featured in the Millions piece tend to be split (though I think the Hillary Mantel and Madeline Miller UK covers are far superior), as are my feelings for MEMOIRS OF AN IMAGINARY FRIEND, which actually published first in the UK.
My opinion regarding which one I prefer changes almost daily.
