What Is The Stranger in My Home About?

At the heart of the novel is Alison, a devoted mother who lives a seemingly idyllic life with her partner Jeff and their teenage daughter, Katherine. Everything changes when a man named Tom Truby knocks on their door with unimaginable news: Katherine isn’t their biological daughter. Fifteen years ago, their babies were accidentally swapped in the hospital.

Suddenly, Alison is forced to question her identity as a mother. Her real daughter, Olivia, was raised by Tom and his late wife. The discovery sets off an emotional and legal minefield, compounded by potential genetic health risks and the psychological trauma inflicted on all involved.

Adele Parks explores motherhood as an emotional, rather than purely biological, bond. Alison’s sense of identity is wrapped in her role as Katherine’s mother, and the revelation forces her to redefine what family truly means.
