The wish / Nicholas Sparks.

Maggie hasn't told this story in years. More than two decades ago, she fell in love. She was sixteen and far from home, waiting to give her baby up for adoption. Bryce showed Maggie how to take photographs and he didn't judge her for the way her belly swelled under her jumper. They had the perfect first kiss. Theirs was a once-in-a-lifetime kind of love. Now, as Maggie sits by the Christmas tree in her gallery telling her story, surrounded by the photographs that made her famous the photographs Bryce never saw her new gallery assistant asks her a question. If she had one wish, what would she wish for this Christmas? Maggie always thought she knew the answer to that question. But before she can say 'I'd go back to that winter with Bryce', she stops herself. It is all she has ever wanted but suddenly here, on this dark night under the twinkling stars, there is something else she wants.
