When a personal vendetta leads to a savage prison escape, Special Agent Sam Rivers must outwit a deadly killer before his family becomes the next target.

Sam Rivers expects a quiet few days at a law enforcement conference, held at Peterson's Resort, deep in the forests of northeastern Minnesota. Joined by his wife and teenage stepdaughter, the special agent for the US Fish and Wildlife Service looks forward to a working vacation. But the wilderness offers no refuge when danger comes looking for him.

After violent offender Angus Moon escapes from a Canadian prison--with help from the mysterious Wilhelmina Gunn--the cunning duo set their sights on revenge against Sam, whom they blame for ruining their lives. The severed head of a grizzly bear appears on a remote bridge known as Grizzly Narrows, luring Sam into a deadly game with high stakes: the life of his abducted wife.

As Angus stalks the woods with calculated brutality, Sam must rely on his instincts, his family's resourcefulness, and his wolf-dog companion, Gray, to track a predator who knows the terrain--and Sam's weaknesses--all too well.

In this sixth installment of the Sam Rivers Mystery series, award-winning author Cary J. Griffith delivers a pulse-pounding wilderness thriller packed with action, psychological tension, and emotional depth. Grizzly Narrows is a gripping tale of survival and vengeance where one wrong step could be Sam's last.
