Wyoming, 1876. For as long as they have lived on the frontier, the Bemis and Webber families have relied on each other. Losing her husband to Cora's indiscretion is another hardship for stoic Nettie Mae. But as a brutal Wyoming winter bears down, Cora and Nettie Mae have no choice but to come together as one family - to share the duties of working the land and raising their children. Bound by the uncommon threads in their lives and the challenges that lie ahead, Cora and Nettie Mae must finally decide whether they can learn to trust each other - or else risk losing everything they hold dear.
