Virginia — Susan Hughes

Fourteen-year-old Ivy is flabbergasted when her childhood friend Virginia claims that she has been visited by an angel who has asked her to bear the child of God. As Ivy struggles to understand and help her friend, she uncovers more secrets, including an apocalyptic plot being devised by Virginia's weird brother, Paul. Ivy suspects Paul's activities must connect in some way to Virginia's claim but she's uncertain how. Soon Ivy finds herself caught up in a chain of events she has no control over.
