Born under the same solstice sky thirteen years ago, Fia and her snow deer Solas have always had a powerful and unbreakable connection. But as Fia's village face a seemingly eternal winter, they turn their sights to Solas and an ancient prophecy that promises the return of sunlight and life, if the ultimate sacrifice is made . . .

 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 might be their only hope. 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 Fia face to bring back the sun and save her village?

A powerful and beautiful tale set in snowy pre-historic Ireland, about hope, kindness and the power of friendship, from exceptional new writing talent, Eilish Fisher, brought to life with stunning illustrations from Dermot Flynn.
