The Mimameid Solution

Ragnarök was only the beginning.
For fans of The Hunger Games, The Maze Runner and The Giver, The Mimameid Solution is a compelling start to a post-apocalyptic trilogy about survival, resilience and finding your place in the world.
Five years after the world he knew collapsed in ecological disaster, Lysander is back in his homeland of Old Scandinavia with his companions, Magdelena and Linnaea. The atmosphere is full of ash, the days are cold and dark and they are constantly under threat from the Celts, who have invaded and are burning the countryside in their wake. When a rogue group of soldiers led by a fiery Lieutenant named Petra offers them refuge in a place called Mimameid, they are tempted by a chance at safety.
But when Mimameid turns out to be more than he bargained for, Lysander must take control of his own fate and decide whether to stay or to go.
