Charlotte Kavanagh's beloved grandma Katarina Sanchez is gravely ill, so when she begs Charlotte to travel to her homeland in Andalucía to uncover the truth behind a mysterious painting, Charlotte agrees. Taking leave from her soul–destroying job and stalled life in Australia, Charlotte embarks on a quest through Granada's ancient cobble–stoned streets and vibrant neighbourhoods. There she meets Mateo Vives, a flamenco guitarist with a dark past, and through him she quickly becomes entangled in the world of flamenco and gypsies that ignites a passion she had thought lost.

But the mystery surrounding the painting deepens, reaching back in time to the war–torn Spain of the 1940s and Charlotte discovers her grandmother's connection to the Spanish underground. Who is her grandmother, really? What is Mateo's connection to her family history? And why is finding answers to a family mystery turning into a journey of self–discovery for Charlotte?

Weighed down by secrets, betrayals and shattered relationships, Charlotte finds herself questioning the true meaning of heritage, family and love.
