Zombie's world

When the most important person in her life became a zombie amelia did what most people would. she kept her. fourteen-year-old amelia has definitely had some bad luck the last couple of years. first, the zombies came. then her parents became infected. all of that she could deal with, after all, she still had her sister mia. then mia got bitten. amelia didn't think she would be able to handle that but then she discovered something unusual. instead of attacking her, mia protected her. not that amelia doesn't appreciate it but she still wants her old sister back, the one who talks instead of growls and doesn't chew on living things. they're heading to a military lab in search of a cure for mia. however, the lab contains secrets that when unleashed make everything they've encountered in the new world seem like child's play. surviving just became a little harder.
