Once there, she receives an unexpected inheritance-a house on the beaches of Madras-and discovers an older sister she never knew she had: Lucia, who has spent her life in a residential facility. Grace's attempts to leave her old self behind prove first a struggle, then a strain, as she discovers the chaos, tenderness, fury, and bewilderment of life with Lucia.
