Havana Year Zero

the long version

"The year is 1993. Cuba is at the height of the Special Period, a widespread economic crisis following the collapse of the Soviet bloc.For Julia, a mathematics lecturer who hates teaching, this is Year Zero: the lowest possible point. But a way out appears: the search for a missing document that will prove the telephone was invented in Havana, secure her reputation, and give Cuba a purpose once more. What begins as an investigation into scientific history becomes a tangle of sex, friendship, family legacies, and the intricacies of how people find ways to survive in a country at its lowest ebb." -- Amazon.com
