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?
