As the twentieth century dawns on the island of Rathlin, a place ravaged by storms and haunted by past tragedies, Nuala Byrne is faced with a difficult decision. Abandoned by her family for the new world, she receives a proposal from the island's aging tailor. For the price of a roof over her head, she accepts.
Meanwhile, the island is alive with gossip about the strangers who have arrived from the mainland, armed with mysterious equipment which can reportedly steal a person's words and transmit them through thin air. When Nuala is sent to cook for these men - engineers, who have been sent to Rathlin by Marconi to conduct experiments in the use of wireless telegraphy - she encounters an Italian named Gabriel, who offers her the chance to equip herself with new skills and knowledge.
As her friendship with Gabriel opens up horizons beyond the rocky and treacherous cliffs of her island home, Nuala begins to realise that her deal with the tailor was a bargain she should never have struck.
