Born under the same solstice sky thirteen years ago, Fia and her reindeer Solas have a powerful and unbreakable connection. But now, struggling to survive a seemingly eternal winter, Fia's village turn their sights on Solas - both for the meat the last remaining reindeer can provide and an ancient prophecy promise that an ultimate sacrifice will once more return sunlight and life to the world . . .

Refusing to allow the worst to happen, Fia and her cousin Mish run from the village with Solas, seeking out the Deer Mother - the mythical being who wakes the sun at the winter solstice and who they believe is their only hope of saving Solas and their village.

But the wilderness is harsh and shadows lurk at every turn. Can they make it to the Deer Mother? And, if they do, what choices will they face to bring back the sun?

A truly timeless novel in verse about hope, kindness and the power of friendship from an extraordinary new writing talent.
