Fifteen years ago, Kate walked out on her family. Moving across the world, from the suburbs of England to glamorous LA, she cut all ties to her former existence and started afresh. Her ex-husband Andrew was left to pick up the pieces, caring for their disabled daughter and angry, confused son. But Kate's past has finally caught up with her. Now, she must return to the life she abandoned and reckon with what she did.

Following a fractured family over a period of twenty years, This Could Be Us is an extraordinarily moving story of family, guilt, love and hope.
