UNFORGETTABLE (4.5) by Cassie Miles: There may be big holes in Jack Dalton’s memory, but he knows that somebody wants to kill him and that he needs to get out of the line of fire and off the radar of the FBI agents who were supposed to protect him. Caitlyn Morris has retired to her family’s mountain cabin, seeking safety from the PTSD that has haunted her since her tour as an embedded reporter in the Middle East. An encounter with Jack brings all her old emotions back. More than that, he could be her entree back into the world of journalism — that is, if they live long enough. Miles piles on the suspense, action and suspects until the terrific conclusion.
