This is at best a B grade effort by an A+ author who brought us ingenious books like “Mr. Perfect”, “Dying to Please”, and “Blood Borne”. It’s a mesh of a murder mystery, and a tepid romance, with a time traveling FBI agent (the heroine), who isn’t nearly assertive enough to be a Fed, or even a convincing cop.
As sci-fi, the time travel story, it was ok, but the author seemed to forget the self imposed rules of what can come through the time portal, and what cannot.
As a romance, the Hero and Heroine were ok, together, but it seemed to me IMO, to be luke warm at best.
As a mystery, it was abrupt, and cut-off, and devoid of clues that would make sense. The time traveling fed used her DNA scanner to sift for clues everywhere - except at the last actual uncontaminated murder scene. It’s like she forgot she had this detecting tool.
I’m a sucker for sci-fi romance and a time traveling story by one of the most talented authors should be a slam dunk, but the neglect of details, and the passiveness of the female who was supposed to be this super-cop brought her off to me as unassertive and borderline incompetent. She should have been in control of the investigation, not following the lead of the local constabulary.
