Joe Dever's 'Caverns of Kalte' is the third gamebook in the fantastic, legendary Lone Wolf series. Following the demise of Zagarna, Lone Wolf is set upon a mission to bring Vonotar the Traitor - renegade Magician - to justice. However, Vonotar has found refuge within the icy wastes of Kalte, a hard, merciless wilderness. Where even the ferocities of nature are against him, Lone Wolf must brave the inhabitants of Kalte then steal himself into the magician's fortress. A great sequel to end the legacy of Zagarna, despite it being a part of the Lone Wolf Novice series (books 1-5). In particular, I found the Ice Barbarians a superb feature to this gamebook.
