Era como si hubiéramos alcanzado el punto crítico mínimo de una curva matemática. Tiene presente una parábola? El cero de abajo, el hueco, el abismo. Hasta ahí llegamos.Corre el año 1993. Cuba está en lo más álgido del Período Especial, un profunda crisis económica tras el colapso del bloque soviético.Para Julia, una profesora de matemática que detesta enseñar, La Habana está en su año cero: el punto más bajo, camino a ninguna parte. Desesperada por tomar las riendas de su vida, Julia se une a Euclides, su colega y ex amante, para emprender la búsqueda del documento que compruebe que el teléfono fue inventado por Antonio Meucci, en La Habana. Creen que esta es la respuesta para proteger su reputación y darle a Cuba un nuevo propósito.A partir de este punto cero, Julia da inicio a una investigación que la acercará a dos hombres que prometen guiarla hasta el documento, y que la verá involucrada en un enredado misterio de pasión, legados familiares y las complejidades de cómo la gente encuentra maneras de sobrevivir en un país que vive la más terrible de sus crisis.

It was as if we'd reached the minimum critical point of a mathematical curve. Imagine a parabola. Zero point down, at the bottom of an abyss. That's how low we sank.

_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, Havana is at Year Zero: the lowest possible point, going nowhere. Desperate to seize control of her life, Julia teams up with her colleague and former lover, Euclid, to seek out a document that proves the telephone was invented by Antonio Meucci in Havana, convinced it is the answer to secure their reputations and give Cuba a purpose once more. _From this point zero, Julia sets out on an investigation to befriend two men who could help lead to the document's whereabouts, and must pick apart a tangled mystery of sex, family legacies and the intricacies of how people find ways to survive in a country at its lowest ebb.
