And Then There was None

All Isa wants to be is to be like her beautiful older sister Elle. Instead, Isa was born with the personality to fight anyone who got in her way and cause mischief. Her sister Elle was never liked that, and she was constantly compared to her. But, when the world is under attack, Isa and her family must go to the safe-haven. There, they would be assigned numbers to the place where they will live until the war was officially be over. Isa was given a much different assignment than that of her family members, instead she must fight whatever was attacking them...and her very annoying, yet highly attractive roommate Chale. In the world they live in now, it is kill or be killed, and Isa would rather kill than be killed.
