After awakening with no memory in a battered outpost at the edge of a frozen world, a stranger is believed to be Thorne, the hated former Engine Master. A child named Orion insists he is his father, while guarded Vanguard Captain Kaelen is forced to call him his partner. To survive the suspicion surrounding him, he restores vital machinery, gathers scarce supplies, and defends the overlooked people of the settlement. As Kaelen begins to see the man beneath Thorne's feared name, lost memories expose a devastating betrayal, a stolen life, and the love they once shared. With raiders closing in and winter threatening everyone, they must fight for their son, their home, and a future together.
