Summary
[official summary from the back of the novella]

Forming a natural border between the Kyanite and Moonglade kingdoms, the Lune Mountains are a long range of snow-covered and human-free mountains, home to the descendants of Dragon Mother Lune.

For many years, Queen Peak and King Alpine have peacefully looked over their kingdom. But all that has now changed.

The actions of the twin sons of Peak and Alpine have altered the course of history, for better and for worse.

This is the story of Cold-Claw and Frost-Paw.
