With a number of Spanish literature afincionados around, and a good number of people that at some point passed through the phase of being 'intermediate level' Spanish speakers, this seems a good place to ask for tips for relatively easy-to-read, clear-written books in Spanish. I would love to order some books in Spanish to keep practicing, but my experience with reading French literature warns me that just the aim to practice is not enough. Reading a newspaper or an article is easy enough, but to finish a whole book you've got to enjoy reading it too. And with a language you're not absolutely fluent in, some books can be more challenging than others. So, a question for those who know their Spanish literature, any recommendations for books in clear and accessible Spanish, without excessively challenging vocabularies?
