Half Faerie (Daughter of Light) (Volume 1)

In the heart of the enchanted world, a young half-faerie struggles to free herself from the shadow of her father's dark ambition. 

Eighteen-year-old Melia lives as an outcast in the Realm of Faerie, along with her two sisters and their faerie mother. Their father has been exiled to the mortal world. He's obsessed with incarnating Umbra--the residue of mortal ash accumulating in the Void. He believes it will allow him to return to Faerie and reunite with his beloved wife. 

It will also start the battle between Dark and Light. 

Melia is determined to protect her world from the repercussions of Umbra's incarnation. By confronting her father, she will shape her destiny and, ultimately, the future of the Whole. 

Whimsical and edgy, Daughter of Light is a spinoff of the 14th century French fairy tale Melusine. A high fantasy with fairy tale elements and an intriguing cosmology, it's a great choice for readers who have loved The Lord of the Rings.
