Anna has been surviving alongside her sorority sisters in a Zombie Apocalypse for months. Against all odds, the group of girls has continued to stay alive with sheer luck and their mismatched set of skills. But once again, their world is flipped upside down with the arrival of unexpected guests. Aliens have invaded Earth.

Aprixians, they're called. With their hulking size and super-human strength, the sorority begins to look to them for protection. Much to Anna's dismay, the aliens aren't leaving any time soon. Especially not when two of them find mates amongst the group of girls.

As the group's former protector, Anna is nothing if not annoyed by the newcomers. She has no need for them and definitely no desire to befriend them. Especially not Drak, the male who can't seem to leave her alone. The very same alien whom she attempted to slay when finding him in her home. Her attempts at removing him from Earth were fruitless. In fact, they only seemed to make Drak like her.

Anna does not have time to deal with him. But when he volunteers to help her on a secret mission… she isn't stubborn enough to turn him away.
