Elementals (#2) Scorch Dragons by Kaufman
After the fateful battle between the ice wolves and the scorch dragons, Anders and his twin sister, Rayna, have been reunited. But there’s no time to celebrate. Anders and his wolf friend Lisabet are still considered threats in the mountain stronghold of Drekhelm. It’s there they learn that the wolves have stolen a weather-altering artifact called the Snowstone.
Every dragon, including Rayna, is now in grave danger. Desperate to broker peace, Anders teams up with a few new flame-breathing friends to stop the wolves’ next plan of attack. Together, these former rivals must go on a perilous quest 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.
