Loki: Winds of Winter

Peace is a fragile thread so easily snapped. When the Five Wight Walkers escape Westeros and disappear throughout the rest of the realms, Loki and Daenerys must handle the threat quickly and quietly. But, knowing Loki's luck, quietly is not going to happen. When the Wight Walkers arrive on Midgard, Loki sends the only people he can trust to deal with the issue: an adult Rhaenar and Ragna Frostborn, his eldest son and daughter!
The two highly trained fighters soon come face to face with the notorious Avengers and SHIELD, but explain the delicate mission they are on to avoid a confrontation. They are paired with Bucky Barnes, the Winter Soldier; and Wanda Maximoff, the Scarlet Witch. Together, they begin to battle the undead as the Wight Walkers begin to gather their forces for a hostile take over of the world of the living.
Loki cannot stay away for long and soon finds himself on the realm he once tried to rule. Cold snows blow and ice is a treacherous element.
Loki can feel the chill of the winds of winter!
