Mirror of Fate - House of Shadow Raven, #1

Never underestimate the power of witches. Demons walk the lands, searching for the next soul to devour. For years, light witches have fought to protect the innocence of mythical creatures, but the magical elements are out of balance, and benevolent covens are becoming extinct. Maura finds a mentor in Sage, a light witch from House of Ashburn, who can help reinforce Maura's light magic and hold back the darkness plaguing the kingdoms.
Together, the two must uncover a spell to stop the dark forces before the blood moon rises in three days. Can Maura and Sage uncover the spell in time before the light is extinguished forever?
