Reborn in the Apocalypse: Seven Days to Stockpile Supplies and Slaughter Zombies

In my previous life, my best friend and boyfriend pushed me toward the zombies as bait. I watched them take all my supplies before I froze and starved to death. Reborn seven days before the apocalypse, I awakened a spatial dimension, frantically stockpiled supplies, and reinforced my safe house. This time, I won't be a saint, and I won't go easy on anyone. The scumbag and that vile woman will pay with their lives, and I'll protect Grandma at all costs! When the apocalypse comes, I'll take my supplies and skills, kill zombies, recruit followers, and live more freely than anyone!”
