Xanthe Charles was born with a severe congenital heart defect. She is shy and lacks confidence after spending much of her childhood in and out of hospital, undergoing life-saving surgeries. A non-identical twin, she has grown up in her sister's shadow and in the over-protective care of her strict Catholic parents. At 26, now a nurse at the local children's hospital and craving independence, she finally decides to leave home. She manages to afford a place of her own and thought life couldn't get any better... until she meets her neighbour, Charlie Brooke. Unbeknown to Xanthe, he's a local celebrity and regular performer in a Las Vegas show. As the relationship grows, so does Xanthe's confidence. Their rollercoaster romance has the makings of a true fairy tale until an ironic twist of fate leaves Xanthe's heart even more broken than when she was born.
