A blizzard. An oath. A war outside and within.

By the winter of 1916, World War I has ravaged the Austro-Hungarian Empire. Eighteen-year-old Renata Zamoyska, Polish countess and doctor-in-training, has lost everything to the Russian occupation: her family, her home, her fiancé. But with the Russians in retreat and the Germans now in charge, life isn't much easier. Wounded soldiers keep arriving from the front, Renia’s house remains in ruins, and the scars of the occupation linger.

When two Polish deserters from the Russian army turn up on her doorstep just before a fierce blizzard, Renia finds herself trapped in her own home alongside people she's long considered enemies. Cut off from the outside world while the storm rages, Renia must fight to survive, grapple with her wartime scars, and decide what justice, freedom, and healing look like for her.
