Sarah Penn and Maggie Reave are sisters, as different as a tabby and a tiger. Sarah has married kind, reliable Leo and settled contentedly into small-town life. Maggie, light-hearted and footloose, has spent fifteen years drifting round the world with a backpack and a cheerful willingness to do any menial job as long as it has no future. But now Maggie has come home, pregnant, and undecided whether or not to keep the baby. And as she dicusses this with her sister, lets slip that she's had an abortion before, and that the father was Maggie's husband. This throws everything into confusion, but Christmas brings reconciliation and a new baby.
