The Other Family by Joanna Trollope
When Richie Rossiter, once a famous pianist, dies unexpectedly, Chrissie knows that she must now tell the truth to their three daughters: their parents were never married. And there is one more shock to come when Richie’s will is read. It seems he never forgot the wife and son he left behind years ago – Margaret, who lives a quiet life of routine and work, and Scott, who has unresolved feelings about the father who left him. Now tow families are left to confront their losses and each other, and neither of them will ever be the same.
