She almost caught him once. Now, he’s back.

For three years, Investigator Cassie Dewell has been on a hunt for a serial killer known as the Lizard King whose hunting grounds are the highways and truck stops where runaways and prostitutes are most likely to vanish. Cassie almost caught him…once.

Working for the Bakken County, North Dakota sheriff’s department, Cassie has set what she believes is the perfect trap and she has lured him and his truck to a depot. But the plan goes horribly wrong, and the blame falls on Cassie. Disgraced, she loses her job and investigation into her role is put into motion.

At the same time, Kyle Westergaard, a troubled kid whom Cassie has taken under her wing, has disappeared after telling people that he’s going off on a long-planned adventure. Kyle’s grandmother begs Cassie to find him and, with nothing else to do, Cassie agrees—all the while hunting the truck driver.

Now Cassie is a lone wolf. And in the same way that two streams converge into a river, Kyle’s disappearance may have a more sinister meaning than anyone realizes. With no allies, no support, and only her own wits to rely on, Cassie must take down a killer who is as ruthless as he is cunning. But can she do it alone, without losing her own humanity or her own life?

Review –

This excellent conclusion to a quartet of loosely related novels that started with 2011’s Back of Beyond finds Cassie Dewell now the chief investigator for the Bakken County (N.D.) Sheriff’s Department. Cassie convinces her boss, Sheriff John Kirkbride, to approve a sting operation designed to entrap serial killer Ronald Pergram, an independent trucker who preys on truck stop prostitutes. Having eluded capture in 2013’s The Highway, the cunning Pergram gets wind of the plan and booby traps his truck, which explodes and kills several local police and feds involved in the operation, including Cassie’s fiancé. In the aftermath, Cassie is suspended and obnoxious county attorney Avery Tibbs subsequently forces her to resign. Meanwhile, Pergram goes on a kidnapping spree that leads to Cassie to contact Bull Mitchell, who we met in the first book when he led Cody Hoyt into the back trails of the park, and together they put together a tracking party and go into the park to hunt down the Lizard King. Cassie along with the ingenuity of Kyle bring down the pervert in an anti climatic end. She is later offered a job in Montana and she and her family settle down once again in new territory but this time, everyone is in agreement.

Just a warning, there is violence and a lot of  edge of your seat action. A good ending to a series that kills off a main character in book one. Just saying.
