Don't let the cover art fool you. I am not reading the Spanish edition but listening to the English language audio version.
Finding books to purchase when Audible holds a twofer or a threefer sail is not always easy since they select 200 or titles to choose from (and many times they are all books I have no interest in). In the most recent sale, I was able to find three titles that I would want to have in my Audible library, where one of the criterion is that it be a book that I would read more than once. I chose Cain because I thought that I should read at least one by this Nobel Prize-winning author.
