Mist Gallows - The Prophecies of Ragnarok, #3

Are you ready for the battle of a lifetime?The end has begun. Ragnarok has arrived as prophesied. The Great Winter has brought Midgard to its knees, and it's only a matter of time before the gods and their armies clash on Vigrid one last time. Desperate to save the realms, Victor leads his friends on a mission to the underworld. He intends to seek out Hel, daughter of Loki and Hodr's lover, and convince their side to stand down and make peace with Odin, therefore averting the war.
But a far greater threat than the reckoning of an ancient feud looms on the horizon. Silje learns that Yggdrasil is dying, and if the Tree of Worlds dies, the worlds die along with it.
