Book 1

Carol really loves Christmas. The decorating and shopping, the Christmas sweaters and music—she wishes it all could be a year-round event. The only downside to the holiday is that she lives in Florida (not exactly the land of snow) and her only family is her Uncle Christopher, who adopted Carol when she was young, after her father's disappearance and mother's death. Her uncle owns a toy company and is super rich—but he's a grinch and a workaholic.
Then, on a magical December trip to NYC, Carol meets her destiny. Santa—the real man with the bag—meets Carol at the top of Rockefeller Center, overlooking the tree. There he explains that Carol is descended from a long line of Defenders of Claus, those who protect and serve Santa. Carol's dad was a Defender. And now Carol has been tapped to fulfill his legacy.
Who would want to hurt Santa? Someone pretty scary and shady, it appears—a masked man who's trying to destroy Christmas! Carol is whisked off to the North Pole on the adventure of a lifetime. Can she help save Santa before it's too late?

Book 2

The battle for Christmas, and the world itself, is about to begin.

When Christmas Carol, a Defender of Claus, is suddenly yanked into a portal by her Elven grandmother, she doesn’t immediately understand what’s happening.

But all becomes clear when she and the Ancient One emerge on the other side of the portal in what’s supposed to be the North Pole: everything’s changed.

Carol’s father is gone. The Defenders of Claus don’t exist. The Elf kingdom has been destroyed. And Santa’s a broken shell of himself.

The jolly world Carol knew has turned into a terrifying place, where the magic of Christmas has been eliminated and everyone lives in fear of the all-powerful Supreme Leader. Someone has traveled back in time to change history, and Carol’s pretty sure she knows the culprit.

Carol and her grandmother, with the help of two ragged boys who have lost everything in the rebellion against the Supreme Leader, track down the only Elf capable of helping their enemy travel through time. The bitter, shimmering creature reluctantly agrees to send Carol back, and she lands in the mid-1800s, when Santa was just getting started and the very first Defender of Claus was found. She must protect Santa and the original Defender and undo the damage her enemy has done or risk returning to a present day that has never known Christmas.
