When rancher Cassidy Casey discovers a frozen body tied to a fence line on her Montana property, she expects the sheriff to investigate. What she doesn't expect is for the death to be written off as a tragic accident. But Cass knows her land, and something about the scene doesn't sit right.
With her sharp-eyed Border Collie Scout alerting to danger at every turn, Cass starts asking questions that no one in the tight-knit community of Frost Valley wants to answer.As Cass digs deeper, she uncovers a scheme that threatens to destroy the valley's family ranches, and a list of suspects that includes her own neighbors. The victim was a smooth-talking developer with a talent for making enemies, and it seems like half the valley had reason to want him gone. When threatening notes and calculated lies start piling up, Cass realizes the killer is still out there and willing to do whatever it takes to keep their secrets buried beneath the snow.With her best friend Ruby bringing casseroles and moral support, and Scout's instincts proving sharper than any detective's, Cass races to solve a murder that everyone else wants to forget.
But in a place where trust runs as deep as the valley and neighbors protect their own, uncovering the truth might cost Cass everything she holds dear. In Frost Valley, some fences are meant to keep secrets in, and some are meant to keep trouble out—but Cassidy Casey has never been one to respect boundaries when justice is on the line.
