At the bedside of her sister Amy who is in a coma after a tragic accident, Moira recounts her life which has been profoundly affected by the intense jealousy she has felt for Amy since she was born. A dark compelling tale, not a cosy read, with a central theme of sibling jealousy, told in lyrical prose in both first and third person. You may struggle to feel any sympathy for Moira's character who comes across as a cold, bitter, self-centred person who has been a poor daughter and a deceitful wife; my dislike for her intensified as the book progressed! The sea is a constant presence in the story and I loved the many and varied descriptions of the Welsh and Norfolk coasts, at times so vivid that you can almost smell and taste the salty air. The ending came too soon, and left me wanting more!
