Beast Quest: Nanook the Snow Monster by Adam Blade

She was bigger than any monster Tom had ever imagined. Her fur was white, her eyes redder than a blacksmith's fire and her ivory claws looked sharper than daggers. Her hideous face was scrunched up with anger and hate, and around her raw, welted neck hung a tiny bell on the end a a gold chain. It glowed with evil energy, Nanook pulled at the chain, trying to tear the bell free, then howled ferociously and stamped a paw on the ground. The whole snow dune shuddered.
