DIVISIBLE MAN: Ten Keys West

Seaborne’s thriller features the return of superpowered action hero Will Stewart.

In this 10th installment in his contemporary adventure series, the author continues the exploits of Will Stewart, an air charter pilot, and his wife, Andy, a detective in Wisconsin’s Essex County Police Department (characterized by her husband as “an equal opportunity juggernaut of justice”). Will and Andy are briefed by FBI Special Agent Leslie Carson-Pelham and her colleagues on the inner workings of a paramilitary insurgency group known as Company W (“The W stands for White and the military grade high-capacity semiautomatic rifles they carry promise supremacy of arms, if not intellect”). Will and Andy have had near-fatal encounters with Company W before and have always been stymied by the compartmentalized nature of the group. “It’s not an organization with a headquarters,” they’re told by Carson-Pelham. “It’s like a cloud or a fog moving across the landscape. Arch conservativism. Racism. White supremacy. Grievance. Fascism by a dozen different names.” The couple are swept up in a complex plot involving the desperate plight of children in a hospice program, with tendrils of corruption and evil extending from Galveston to the Florida Keys. The narrative includes a number of suspicious figures, some of them connected to an evil pharmaceutical company that will arouse readers’ suspicions right from the start. Though the narrative gives a generous amount of the spotlight to Andy, Will is a natural scene-stealer by virtue of his actual superpowers: He can both fly and vanish from sight.

Considering the outsized, comic-book premise, it continues to be downright amazing how grounded Seaborne’s world consistently feels. Yes, Will Stewart has some Marvel-style paranormal gifts, but both his abilities and personality are so thoroughly fleshed out and believable that, in no time at all, the reader matter-of-factly integrates these fantastical elements into the standard heroics-and-gunfire action without a second thought. “This isn’t one of your silly action movies where all the clues line up in the third reel,” Andy deadpans. “It’s hundreds of hours of boring investigative work, connecting dots, scouring phone records, scraping through emails and texts, building cases.” This latest entry in the series maintains the same grounded, workaday feeling, but both Will and Andy consistently strain against it—they’re full-fledged action heroes, always ready to respond with Hollywood-style quips and larger-than-life violence. The author effectively fleshes out even minor walk-on characters, and his portrayal of the loving relationship between his two heroes continues to be the most satisfying aspect of the series, the kind of three-dimensional adult relationship remarkably rare in thrillers like this one. The author’s skill at pacing is razor-sharp—the book is a compulsive page-turner right up until the obligatory exposition dump near the end. The descriptions of the actual workings of Will’s powers are uniformly gripping; it makes the book feel like the best possible combination of the Odd Thomas novels of Dean Koontz and the Jack Reacher novels of Lee Child.

An irresistible, high-stakes, cross-country adventure about a man with amazing gifts.
