Welcome to Knife's Edge, Alaska, where the four Osprey brothers return from military service with shadows in their eyes and secrets in their hearts. As danger looms, new romances ignite, and these rugged men must fight for love . . . and survival.

Damian Osprey spent years in intelligence, where secrets were currency and trust was a liability. Taking a job as head of security at a remote research facility deep in the Alaskan wilderness brings him back to the land he once called home. It should be routine. But the facility sits at the center of a pattern Damian can't ignore, and every answer he finds only leads to darker questions.

Stella Osprey has never stopped watching his back. Their marriage began as part of an undercover operation, but the fire between them was never pretend. She's been working in the shadows ever since, following a trail of secrets that leads her to Alaska. And back to the only man she was never supposed to love.

When Damian finally catches the woman he knows has been moving just out of reach, the heat between them ignites fast and fierce. But with secrets buried in the wilderness, a ruthless killer stalking the land, and a conspiracy that could destroy them both, trusting each other again could cost them everything.
