New York Times bestselling author Cecelia Ahern spins a witty, warm, and wise modern-day fable of love, regret, hope, and second chances.

extremely successful executive, Lou Suffern is always overstretched, immune to the holiday spirit that delights everyone around him. The classic workaholic who never has a moment to spare, he is always multitasking while shortchanging his devoted wife and their adorable children. And ever since he started competing for a big promotion, he has barely seen his family at all.

One frigid morning in an uncharacteristic burst of generosity, he buys a cup of coffee for Gabe, a homeless man huddled outside his office building. Inspired by his own unexpected act of kindness, Lou decides to prolong his charitable streak and contrives to get Gabe a job in his company's mailroom. But when Gabe begins to meddle in Lou's life, the helping hand appears to be a serious mistake. Gabe seems to know more about Lou than Lou does about himself, and, perhaps more disturbingly, Gabe always seems to be in two places at once.

With Lou's personal and professional fates at important crossroads and Christmas looming, Gabe resorts to some unorthodox methods to show his stubborn patron what truly matters and how precious the gift of time is. But can he help him fix what's broken before it's too late?
