Troll

In the Vikings' world of Midgard, where the winds of fate blow harsh and the shadows of the past still loom, there lives an orphan stable-hand named Ash. Forced to work under a tyrannical stable master, he is discontent with his station in life, dreaming of greater things and adventure.

But be careful what you wish for, as the gods might just hear you, for in the heart of the land, a terror has awoken, the draugr, long thought banished, now roam the land once more. As his mysterious heritage comes to light, so it falls upon Ash to reluctantly seek the cause of this resurgence, and to restore balance to the realm.

His quest takes him on an unexpected journey right to the heartland of humanity's oldest enemy, the trolls, where dark deeds and terrifying magic are threatening to throw Midgard into Ragnarok - the end of the worlds.
Troll is a deep dive into Norse mythology and Scandinavian superstition, a thrilling YA adventure where gods and giants play a game with human pawns and the fate of the nine worlds is the prize.
Thus begins the story of Ash the Viking, in the first instalment of the Norse Saga trilogy.
