For years, the two kingdoms of Delmaa and Prantarr coexist peacefully. But when months of unprecedented rainfall cause a landslide of mud and rock to close the only route of commerce between the two countries, that peace is shattered. With war erupting between the nations, Princess Cristiana "Ana" of Prantarr and her brother must flee for their lives over a range of treacherous mountains to the safe land of Lentanne. En route, they meet Darius, a mysterious Delmish stranger, who joins them on their journey.

When a fierce attack by a falcon kills, two must continue their journey alone.

Confronted by dragons, mermaids, the forces of nature, and an array of magical creatures, they struggle to find their way over the mountains.

Through it all, Ana learns to believe in herself and discovers just how strong she really is, for the hardest task is yet to come. Everything Ana knows to be true is turned upside down and a choice must be made...
