Ungone by Hannah Patterson

Eve is attempting to come to terms with her ageing mother, who has dementia and lives in a care home, and employs Erin, a total stranger, to visit the home and pretend to be her.
 
The act has profound consequences, as all three women begin a process of doing, undoing and redoing, with complicated and ultimately necessary truths revealed about each of their lives.
 
Ungone tells the story of a single decision-a deceptively simple thing-through which the fractured, multi-layered nature of identity and the self is both revealed and interrogated.
