Kim can't wait for the hockey camp in Trondheim during the winter holiday, especially since his best friend Alex is coming all the way from Fredrikstad to join him.
But the excitement quickly turns into worry when Alex starts hanging out with Kim's arch-enemies from Ørn (Eagle). Suddenly, the loyalty between the two boys who have been best friends for years is put to the test. And why is Mia, the girlfriend of Kim's biggest rival Arnt, sending mysterious smiles in Kim's direction?

Between rough hockey tackles, cup matches, and an upcoming school dance, the winter camp turns out to involve far more drama than Kim had imagined.

This is the fast-paced sequel to Puck Off, a series for readers aged 9–12 about ice hockey, friendship, sports, crushes, and rivalry. The books have been praised for their authentic portrayal of the hockey world.
