Cold Fire by Dean Koontz. excellent nailbiter. Jim Ironheart is a Lifeline for strangers that are about to die. he saves certain people from murder, drowning, etc and wants no reward or publicity. a reporter, Holly Thorn, becomes enamoured of this stranger and sets out to find him and find out his secrets. i have also listened to Odd Thomas, another Koontz book that i enjoyed tremendously. he has a sequel out now, Forever Odd, also featuring that most excellent character.
