At nine years old, Frankie Presto is sent to America in the bottom of a boat. His only possession is an old guitar and six precious strings. But Frankie's talent is unique, and his amazing journey weaves him through the musical landscape of the twentieth century, from classical to jazz to rock and roll, with his stunning talent affecting numerous stars along the way, including Hank Williams, Elvis Presley, Carole King and even KISS. Frankie becomes a pop star himself. He makes records. He is adored. But his gift is also his burden, as he realises, through his music, he can actually affect people's futures -- with one string turning blue whenever a life is altered. At the height of his popularity, Frankie Presto vanishes. His legend grows. Only decades later does he reappear, to change one last life . . .
