Girl, damaged brother, abusive uncle, drowning
An unnamed girl in rural Catholic Ireland grows up beside her older brother, left cognitively impaired by a brain tumour treated in early childhood, with a devout, harsh single mother. At thirteen she is sexually abused by her uncle and then spends her teens and university years in compulsive, degrading sexual encounters. When the brother's tumour returns and he dies, she seeks out violent sex, then walks into a lake and drowns.
