Eight-year-old Terry McQuinn’s life changed one snowy Christmas Eve on the coast of Maine when he glimpsed the summer people’s world previously unknown to this caretaker’s son. Serenity Cottage was a place of beauty and privilege owned by the luminous Halworths – but in the blink of an eye, tragedy left them in ruins. Determined not to follow in his father’s footsteps, Terry grew up to become a high-flying Hollywood film agent – but he has lost himself along the way. When he is called back to Maine by his father’s death, he finds a note that stops him cold: Open Serenity for Christmas. No one has been in the house in thirty years. Although Terry’s first instinct is to leave it all behind, he discovers that Katherine Halworth, the girl he remembers from that fateful night, is the new owner. With her arrival imminent, Terry’s past comes rushing back and he soon learns that it’s never too late to forgive – and never too late to love.
