Ragnarok, Vol. 6: Midnight's Masters

The city of Prontera continues to be attacked by the flying fortress of Himmelmez, the queen of the valkyries, and servant of Freya. Her goal is to seize the Heart of Ymir, which will allow her to reshape Midgard however she wishes! Chaos and Loki team up to fight the legions of undead creatures she has awakened from death, but their battle is pointless if they cannot reach Himmelmez herself. Meanwhile, Fenris and Iris are engaged in a life or death struggle to keep the Heart from being taken by Bijou, a powerful witch who seems to have been sewn together from corpses. Ragnarok is a fast moving comic from Korea that never lets go of the action, even though Lee's art is at times hard to follow. He is inventive and a master of evolving plot. All of the characters seem real, even the evildoers. Even though this is Volume 6, you still feel as though there is a whole universe out there to explore in later installments. Good book! I would also recommend the anime Twelve Kingdoms, Escaflowne, and there's even an online Ragnarok game that allows you to further explore the world that we see in the manwha.
