Fiction by Patricia MacDonald
This story begins with a kidnapping. Anna's little boy disappears at the age of four. The good news is: she gets him back. The bad news is: it takes eleven years. So the child who comes home is not the sweet toddler who left; he's a confused and sullen teenager. The "stranger in the house" is her own son. But there are mysteries still to come...
This was a good thriller!
