"Tina didn't know what she was doing here. Why was she here? It was such a good idea on paper, like all her ideas, in her head, in advance. But in reality it was a mistake." Tina's sister Meg died in a childhood accident, and for almost forty years, Tina has secretly blamed herself for her twin's death. During a visit to her Uncle Edward and his sister Lucia, who both harbour dark secrets of their own, Tina makes a discovery that forces her to question her memories of the day Meg died. As Tina finds the courage to face the past, she unravels the mysteries of her estranged parents, her beautiful Aunt Simone, the fading, compassionate Uncle Edward, and above all, the cold, bitter Aunt Lucia who casts a long shadow over them all.
