Every year Molly visits her Grandma and Grandpa for Christmas. This year a surprise waits for her in the attic of her grandparent's home at 1225 Evergreen Lane. An old leather-bound book, a bright red coat with furry white cuffs, and a secret that has never been shared, . . . until now. Molly is old enough to be in on the secret, and Grandpa needs her help this Christmas.

When Molly falls asleep during one of Grandpa's stories, her eyes open to a magical world. Santa needs one more reindeer to join his sleigh's team. He and the elves want a young reindeer named Socks, but she is afraid to fly. And time is running out.

Join Molly and Socks as they learn to believe in themselves. Their friendship helps each be brave when it matters most. But can they save Christmas? And when Molly wakes in her grandfather's arms, was any of it real?
