Christmas Apocalypse: Reborn with Infinite Survival System

In her past life, Elena was the perfect wife. She gave her husband, Robert, everything, until the world ended. When the apocalypse hit, he, his greedy mother, and his spoiled sister locked her outside their safe house, using her as a meat shield for the freezing, mutated horrors so they could escape with her supplies.

As Elena froze to death, she swore a bloody vow of revenge.

Then, she opened her eyes. It was November 25th. Exactly thirty days before the "White Christmas" Ice Age that would plunge the world into eternal winter.
