When Alex and Michael travel to the Alps with their family to celebrate their great-grandmother's hundredth birthday, the last thing they expect is to be thrown into an adventure where worlds collide and everything is not what it seems...
The two children arrive in the valley at the foot of The Dragon of Ice, a great glacier and the cold heart of a centuries-old legend. Their great-grandmother has arranged for them to go climbing, enlisting a geologist and a mountaineer to accompany them on their ascent. But as an ancient spell takes hold, the legends of the valley become reality, and Alex and Michael are transported to a medieval world of witchcraft, dragons and a devil king. Can they overcome fear and will heroism prevail?
