It's Christmastime in New York City when the impossible happens. In a poor, basement apartment a puddle of city water suddenly freezes into a sparkling circle of dazzling ice. Hundreds of visitors are mysteriously drawn toward the gleaming mirage and what lies within. But why has this miracle appeared in Kelly O'Sullivan's home just days before Christmas? And why will it melt at the stroke of midnight?

Kelly promised herself she would never be a chauffeur like her dad and grandfather, but she is desperate to provide for her three-year-old daughter, Rose. Rose's medical bills are mounting and Christmas is coming. Kelly quickly lands a job, not because she's qualified, but because nobody else wants it.

Her new client, Marcus Irving, is an egotistic billionaire, notorious for problems of his own. Although Kelly resigns to mind her own business, it is impossible to be stuck inside a Rolls Royce all day long without getting to know this family, quite personally: the quirky thirteen-year-old son, the pampered girlfriend, and the miserable dog walker. Secrets are shared and truths leaked by everyone, and Kelly quickly becomes not only their driver but their confidante, mentor, and even friend. At least to everyone but Marcus Irving. He prides himself on running his family like he runs his global company-but that is the very problem. Kelly sets out to prove him wrong, only triggering a life-threatening disaster.

Ridden with failure and guilt, Kelly returns home to her dilapidated apartment to find that stubborn puddle of city water is back again, but this time it has frozen into a shimmering patch of ice. But what Kelly sees inside this Christmas miracle is beyond anything she could ever imagine.

What hundreds of visitors see inside this sparkling circle of ice will change their lives forever.
