When Stewart moves into his remote Norwegian cabin to focus on his writing, he expects peace, quiet, and maybe some snow. What he doesn’t expect is Grim—a tiny, sticky-footed troll who insists the cabin technically belongs to him, has eaten half of Stewart’s porridge, and is determined to meddle in every aspect of his new tenant’s life.

Through adventures involving cross-country skiing, impossible swordfish catches, wild troll parties, and encounters with Norway’s magical creatures, Stewart discovers that moving to Norway means embracing an entire magical world he never knew existed.
