Who is Sarah Lawson

Who is Sarah Lawson is a psychological thriller.
How would you feel coming home to find a family living in your house who call you Sarah, tell you your brother's name is Andy, and insist that you should be ashamed of calling the police for help?

My name is Rowena Shaw and I've never seen any of them before.

They are total strangers. It's Thursday and it's just the beginning.
Only private investigator Richie Stevens and his PA can unravel the mystery of Who is Sarah Lawson and discover why the woman everyone seems to know as Sarah insists she is someone else entirely.
