War has arrived in Kypria. Unlikely allies unite and mighty warriors clash. To protect the people and land she loves, Arisa must fulfil her destiny and overcome her past demons.

Arisa flees to Kengia with Takai in pursuit only to find that her father's homeland provides little comfort or safety.

In the capital, Lochlen, Arisa trains to harness all of her powers but meets blockages in the form of distrusting tribal chiefs, adversarial family members, and conflicting feelings about Takai and a fascinating Kengian Custodian.

In Lamore, the fearsome Northem fleet arrives with a mysterious navigator - a silver-eyed girl with incredible powers...powers that she uses to weaponise firesky after Amund refuses to help.

Lamore and the Northemers join forces and armed with the devastating new firesky weapons declare war on Kengia and the Lamorian rebels.

Kypria's only hope of salvation is the Water Catcher and two equally powerful ghosts from the past.
