Perfect Soul by S.J. Hermann

Raised to be the PERFECT Daughter.
To be the PERFECT Christian.
To be the PERFECT Soul.
In a town of PERFECT sinners.
Nikki was brought up to be the perfect daughter. Raised on the word of God by her parents, who kept her on the correct path with punishments if she strayed from her faith, Nikki was the perfect Christian. A respected citizen in the small religious town of Perfect, Illinois, Nikki held firm to her beliefs.
Until her heritage returned to claim her soul.
Guided by mysterious entities who claim to be her true family, Nikki is shown the haunting secrets of not only the town she holds close to her heart, but also her parents and friends. Discovering that Perfect is a dark and twisted place, her faith is put to the test and sends her spiraling down a path of insanity, for which there may be no escape.
