Inside the Echo (The Flint K-9 Search and Rescue Mysteries, #2)

K-9 handler Jamie Flint and her team – both human and canine – search for a group that's mysteriously vanished during a dog sledding expedition for battered women in Maine's Mahoosuc Mountains. When the authorities learn that a rogue gunman was at the heart of the disappearance, the question turns to which abusive partner is behind the violence. Jamie Flint, herself a survivor of domestic abuse, is haunted by memories of her own experiences as she and her dog, Phantom, fight to find the missing women before the shooter does.
