The Singing Star — Barbara Gaskell Denvil

Skarga has discovered love but not safety. War is imminent, but no battle will be fought on equal terms. The great ice halls, the glaciers, and the vast horizon pause as the hoards from the south march forwards. But they cannot possibly understand what is waiting for them and nothing is exactly as it seems. There is a good deal more to discover and Thoddun is the ultimate puzzle. The swirling arctic sky sings passion and hatred, of cruelty and kindness, of peace and destiny! But in the end victory will be frozen in the eternal ice.
