After the fateful battle between the ice wolves and scorch dragons, Anders and his twin sister, Rayna, have been reunited. But there's no time for celebrating. Anders and his wolf friend Lisabet are hiding away in the mountains of Drekhelm under the watchful eye of the dragon high council. They are perceived as threats, and only the leader of the dragons can keep them safe.

Then the temperature in Drekhelm starts to drop throughout Vallen, threatening the lives of the Scorch Dragons. Suddenly, the dragons suspect that the two young wolves are spies for their old pack-that they helped them steal a weather-altering artifact called the Snowstone. The artifact puts everyone including Anders' twin sister, Rayna, in terrible danger.

Desperate to broker peace, Anders enlists the help of a few new flame-breathing friends to stop the wolves' next plan of attack. Together, these former rivals must go on a perilous journey to find the scattered pieces of the Sun Scepter, the only artifact that can counteract the Snowstone. Because if either device goes unchecked, all hope for a truce will be lost.
