Not always an easy read, but a compelling story of two sisters. Ollie is the sun around which her family revolves. Ollie also has severe mental health issues and blows in and out of their lives, causing chaos. Amy is the diligent, fastidious younger sister who spends her life cleaning up and making herself small. The story is told from Amy‘s point of view of loving, and sometimes hating, her sister and her effect on her own life.
