Troll Princess Horra Fyd and young druid Rowan team up to reverse the evil Erlking's spells and save the creatures across the Wilden Lands. However, Fairy Princess Glory Toppenbottom is still a thorn in Horra's side. After Horra and Glory have a heated fight, Glory sneaks out of the castle. She is bent on finding the Erlking to reverse the hex he cast on her. This creates a political disaster when the Glory's sister announces she's coming to retrieve Glory.

Angered by Horra's treatment of a royal guest, King Fyd proclaims Horra to be Queen Bearer. She becomes the ad hoc ruler, freeing her father from the scandal. Shocked, Horra assents. Her first move is to find the missing fairy princess before it becomes an interkingdom war. They form a search party and leave.

The Erlking stalks their every move. When the only choice points them toward the Riven, a cursed hidden land, they don't hesitate. They find Glory is already there, but are immediately separated. The trio find the Riven is nothing like anyone imagined. Will they survive the Erlking's magical traps, or will they, like everyone else, perish within its borders?
