The Property of Blood - Shmuley Myers Novels, #3

When a runner finds the bloodless, mutilated body of a woman who might have been pregnant on an Austin jogging trail, Detective Shmuley Myers and his Preborn Investigation Bureau partner, Jethro Waters, are pulled into a hunt for a serial killer with ritualistic methods and an unknown motive. The body count of young victims, most members of a primitivist church, rises as the Passover and Easter holidays approach.
Claims about Jewish use of Christian blood in rituals and the resulting demonstrations inflame the investigation. Complicating matters is Shmuley's relationship with his GodForce partner: Shmuley and his wife are part of Upline-a movement helping women seeking freedom from reproductive tyranny. Jethro's job is finding and stopping feticiders-and members of Upline. Shmuley has no clue where the search will lead-or how close to home the killer's violence will get.
