Fort Freek — George R.R. Martin

This Repairman Jack book from F. Paul Wilson, Bloodline, the eleventh in the series, follows the New York Times bestseller, Harbingers.

Jack has been on hiatus since the events in Harbingers. With his lover Gia's encouragement he dips a toe back into the fix-it pool. Christy Pickering's eighteen-year-old daughter is dating Jerry Bethlehem, a man twice her age. Christy sensed something shady and sinister about him, so she hired a private investigator to look into his past. But the PI isn't returning her calls. Will Jack find out why?

Jack learns there's a very good reason for the unreturned calls: The PI is dead, a victim of a bizarre water-torture murder. As Jack delves into Jerry Bethlehem's past he learns that the man is not who he says he is. Who―and what―he is will have a devastating effect on Jack's life and future, adding another piece to the puzzle of who he really is and why he's been drafted into this cosmic shadow war.
