Threshold by G. M. Ford
Between the end of his marriage and the excessive force complaints against him, Detective Sergeant Mickey Dolan is running out of chances. When a powerful and connected city councilman reports that his wife and two daughters have disappeared, Dolan is assigned the case-knowing full well that his career is riding on the outcome. While investigating, Dolan meets Eve Pressman and her remarkable daughter, Grace. Gifted with the ability to bring people out of comas, Grace is reluctant to be thrust into the public eye but determined to help those in need. Eve and Grace may know where Councilman Royster's family is and the terrible truth that sent the three of them into hiding in the first place. Now, Dolan faces the toughest choice of his career: is he still a good cop if he has to do the wrong thing?
