Random circumstances brought them together. Love made them family. With Jo O’Malley’s busy career as a lawyer in Chicago, she rarely gets home to Idaho, but this year is different. Her little sister is getting married on Christmas Eve and she has two whole weeks to spend in the snow-covered mountains, with the three foster sisters she loves and Maddie, the woman who made them a family fifteen years ago. Things get off to a rough start when the wedding is canceled, but Maddie asks them to enjoy their holidays together at the festive lodge as planned, in order to console their sister. It’s straight forward enough until Jo, through a chance encounter with a gorgeous golden retriever, runs into Luke, a boy she knew from her early childhood when she spent all her time at the local library. Jo’s not sure how to handle the unexpected attraction and her new feelings for Luke, who is all grown up now, handsome, and as kind as ever. He’s set on staying close to his family in Granite Ridge and she has a plane ticket back to her life in Chicago after the new year. Are the sparks between them merely due to the nostalgia of the season, or will Luke open Jo’s heart to the prospect of passion for something beyond her career?
