Eva has spent the past three years burying herself in her work, trying to forget the heartbreaking events of the Christmas that ripped her world apart. This year, the last thing she wants is to attend her friend's weekend-long Christmas party. But at her husband James' insistence, here they are.
When Eva--overwhelmed by bittersweet memories--tries to sneak back to London in the middle of the night, she is visited by the ghost of her beloved grandmother. Gran tells Eva that if she doesn't face her fears head-on and stop shutting out her loved ones, she risks losing them all forever.
When Eva wakes on Christmas morning, she finds herself living not her own life, but that of her hardworking assistant, Diana, whose overflowing inbox isn't the only secret she's been keeping. The next day, she wakes on Christmas morning again, this time in the body of her best friend's little sister. As Eva lives the same day again and again through the perspectives of her friends, she is offered a glimpse into the lives of those she has been pushing away. With each Christmas Day comes a new lesson--and an insight into the secrets and struggles her loved ones have been hiding. To move forward, Eva must let go of the past. But is it too late to fix her future?
