__Santa's missing, robots are ruling, and Christmas is on the line. Can Aria and Liam save the holiday before it's too late?__In Sommetville, the Wild Ice Gliders Christmas race is all anyone can talk about, and Aria and Liam are ready to win. But one wild twist on the ski ramp catapults them straight into Santa's hidden village at the North Pole, where they make a startling discovery: Santa has been kidnapped, and Christmas is in serious danger.

Now it's up to Aria and Liam to step in. But the North Pole isn't the cheerful wonderland they imagined. Robots have replaced the elves, the village chief refuses to believe anything is wrong, and a familiar villain-one who's tried to wreck Christmas before-may finally succeed this time.

If Aria and Liam can't track down Santa and bring him back safely, there may never be another Christmas.

Get ready for a fun, fast, and festive adventure that will keep kids aged 8 to 12 turning the pages.
