Norse Mythology - The Nine Realms Cycle

The light is extinguished. The prophecy is absolute. The end of the world begins with a lie. In the golden fortress of Asgard, the gods believe they are immortal. Queen Frigg has secured an oath from every living thing to protect her perfect son, Baldr-but pride blinds her to the single flaw. A small, inconsequential sprig of mistletoe. Loki, the Trickster God, consumed by an ancient, unforgivable grievance, finds the loophole.
His vengeance is not an act of war, but a surgical strike against the heart of Asgard. What follows is a descent into cosmic tragedy: a blood-oath shattered, a brother forced to slay a brother, and the swift, terrifying descent into Fimbulvetr-the Winter of Winters. This is the definitive Norse Mythology retelling you've been waiting for. Witness the terrifying, intimate collapse of the cosmos: The crippling guilt of Odin, whose paranoia leads him straight into the jaws of the Wolf, Fenrir.
The epic, poisonous final duel between Thor and the monstrous Midgard Serpent. The agonizing, eternal punishment of Loki-bound by the sinews of his own kin, attended only by the fierce loyalty of his wife, Sigyn. The desperate, chaotic charge of the Einherjar against the armies of fire and the dead. When the Sun and Moon are devoured, when the gods fall in brutal, fatal duels, and when Asgard is consumed by fire, what remains? Only a handful of survivors, holding the heavy, quiet promise of rebirth.
If you love emotional epic fantasy that explores fate, failure, and the ultimate price of power, prepare for the Twilight of the Gods.
