Blood atonement / S.M. Freedman.

Grace's healing solitude is shattered when she becomes a suspect in a gruesome series of murders. Grace DeRoche escapes her community of Brigham, a settlement of the Fundamentalist Mormon Church, and works to prosecute Brigham's leaders. But when loyalists, including her own family, commit mass suicide to avoid jail, Grace retreats into solitude. Wracked with guilt and suffering from dissociative identity disorder brought on by childhood abuse, Grace's life is fragmented and full of blind spots. Dissociative triggers are everywhere, and she never knows when an alter personality will take the reins. When other Brigham escapees die under suspicious circumstances, Grace's tenuous hold on reality crumbles. Notes left at each scene quote scripture and accuse the deceased of committing sins so grievous atonement can only be achieved through the spilling of blood. As evidence mounts against her and one of her alter personalities becomes the prime suspect, Grace must determine if she's a murderer or the next victim.
