December 1952. While the young Queen Elizabeth II finds her feet as the new monarch, she must also find the right words to continue the tradition of her late father’s Christmas Day radio broadcast. But even traditions must evolve with the times, and the queen faces a postwar Britain hungry for change.

As preparations begin for the royal Christmas at Sandringham House in Norfolk, old friends—Jack Devereux and Olive Carter—are unexpectedly reunited by the occasion. Olive, a single mother and aspiring reporter at the BBC, leaps at the opportunity to cover the holiday celebration, but even a chance encounter with the queen doesn’t go as planned and Olive wonders if she will ever be taken seriously.

Jack, a recently widowed chef, reluctantly takes up a new role in the royal kitchens at Sandringham. Lacking in purpose and direction, Jack has abandoned his dream to have his own restaurant, but his talents are soon noticed and while he might not believe in himself, others do, and a chance encounter with an old friend helps to reignite the spark of his passion and ambition.

As Jack and Olive’s paths continue to cross over the following five Christmases, they grow ever closer. Yet Olive carries the burden of a heavy secret that threatens to destroy everything.

Christmas Day, December 1957. As the nation eagerly awaits the Queen’s first televised Christmas speech, there is one final gift for the Christmas season to deliver…

Everyone knows that Addie Fullbright can't keep a secret. Yet, twelve years ago, as her best friend lay dying, she entrusted Addie with the biggest secret of all. One so shattering that Addie felt she had to leave her hometown of Starlight, Alabama, to keep from revealing a devastating truth to someone she cares for deeply. Now she's living a lonely life, keeping everyone at a distance, not only to protect the secret but also her heart from the pain of losing someone else. But when her beloved aunt, the woman who helped raise her, gets a shocking diagnosis and asks her to come back to Starlight to help run the family bakery, Addie knows it's finally time to go home again.

Tessa Jane Wingrove-Fullbright feels like she's failing. She's always been able to see the lighter side of life but lately darkness has descended. Her world is suddenly in shambles after a painful breakup, her favorite aunt's unexpected health troubles, and because crushing expectations from the Wingrove side of her family are forcing her to keep secrets and make painful choices. When she's called back to Starlight to help her aunt, she's barely holding herself together and fears she'll never find her way back to who she used to be.

Under the bright side of the stars, Addie and Tessa Jane come to see that magic can be found in trusting yourself, that falling apart is simply a chance to rise up again, stronger than ever, and that the heart usually knows the best path through the darkness.
