Divine by Blood by P. C. Cast

A stranger in two worlds

Conceived in a lie and trapped in a tree throughout her gestation, Morrigan's birth was truly magical. After that start, she spent the next eighteen years raised as a normal girl in Oklahoma.

Upon discovering the truth of her heritage, her rage and grief take on a power of their own, carrying her back to the world of Partholon. Yet, instead of being respected as the daughter of the goddess Incarnate, Morrigan feels like a shunned outsider.

In her desperation to belong in Partholon, she confronts forces she doesn't fully understand or control. And soon a strange darkness draws closer . . .
