Magnus Odinson and the Monsters of Ragnarok

Ragnarok, the End of the Nine Worlds, the Doom of the Gods, has Begun! Magnus Odinson thinks he is a normal boy with a mad mother, until he is sent to the World of the Dead, escapes an undead dragon, and is rescued by the gods who take him to Asgard where he learns that the reason he is called Odinson is that he is truly the Son of Odin, Father of the Gods. Learning the power of the Runes, and with help of the headstrong Annika and the trickster Logan, Magnus searches the Nine Worlds, fighting Frost Giants, tricking Dwarfs, escaping Dark Elves, and confronting a powerful dragon, to find the magic necessary to stop the three Monsters of Ragnarok, who are impossible to kill, and wish to destroy the Nine Worlds forever...
