INVISIBLE HELIX | Kirkus Reviews

The feds must protect an accused criminal and an orphaned girl.

Maybe you’ve met him before as protagonist of The 6:20 Man (2022): Ex-Army Ranger Travis Devine, who’d had the dubious fortune to tangle with “the girl on the train,” is now assigned by his homeland security boss to protect Danny Glass, who’s awaiting trial on multiple RICO charges in Washington state. Devine has what it takes: He “was a closer, snooper, fixer, investigator,” and, when necessary, a killer. These skills are on full display as the deaths of three key witnesses grind justice to a temporary halt. Glass has a 12-year-old niece, Betsy Odom, and each is the other’s only living relative—her parents recently died of an apparent drug overdose. The FBI has temporary guardianship of Betsy, who’s a handful. She tells Travis that though she’s not yet 13, she’s 28 in “life-shit years.” The financially well-heeled Glass wants to be her legal guardian with an eye to eventual adoption, but what are his real motives? And what happens to her if he’s convicted? Meanwhile, Betsy insists that her parents never touched drugs, and she begs Travis to find out how they really died. This becomes part of a mission that oozes danger. The small town of Ricketts has a woman mayor who’s full of charm on the surface, but deeply corrupt and deadly when crossed. She may be linked to a subversive group called “12/24/65,” as in 1865, when the Ku Klux Klan beast was born. Blood flows, bombs explode, and people perish, both good guys and not-so-good guys. Readers might ponder why in fiction as well as in life, it sometimes seems necessary for many to die so one may live. And what about the girl on the train? She’s not necessary to the plot, but she’s a fun addition as she pops in and out of the pages, occasionally leaving notes for Travis. Maybe she still wants him dead. 

Fast-moving excitement with a satisfying finish.
