More Than Survival — Kate L. Mary

Lucy was just nine years old when a deadly virus swept the country, killing most of the population and turning them into zombies. For the past eleven years she's lived in seclusion with her Uncle Seamus, a prepper who was more than ready for the end of the world. But all of Lucy's skills are put to the test when Seamus disappears, leaving her to face the harsh winter on her own. Sawyer went into the mountains to escape his past, and when stumbles upon Lucy in the middle of a blizzard, he doesn't think he's ready for the responsibility having another person in his life will bring. Only, Lucy isn't as helpless as she first appeared, and as they brave the long winter together, Sawyer will soon come to learn that even at the end of the world, there's more to life than just survival.
