The Umbra Tales - Mia and the Lightcasters

Nubis has been plunged into the Darkness by the shadowy Reaper King - a figure children know only through their nightmares. When his minions capture her parents and take over the city, then Mia, her friends and her little brother must travel across the Nightmare Plains to reach Stella, the City of Light. But getting there isn't going to be easy. Mia must learn to harness her umbra taming abilities if she stands any chance of confronting the king and rescuing her parents. If she can't, she'll lose her family - and her soul - to the Darkness forever . . .
