My Cat is Called Odin

Aldo's cat is called Odin. He has only one eye, like the Norse god of poetry and war. In fact, he IS Odin....! Aldo and his two best friends from Comic Book Club have been training to save the world. They've mastered fighting battles (with wooden swords), Morse code, and superhero skills, despite the annoying antics of Aldo's little sister, Petra. The day Odin suddenly appears, they are swept up in truly epic adventure... Yggdrasil, Tree of Life and Death, has mistakenly opened its portal and unleashed Fenrir, the gigantic, evil wolf from Norse mythology, into the world. Can Aldo, his friends and Odin's cat army defeat the Beast before the next full moon, saving kidnapped Petra, themselves and the Earth?
