?When an antisocial apocalypse ?prepper? is the only person in her small town uninfected by a virus transmitted through the trial of a ?telepathic phone?, she must stop preparing for the world?s end and start saving it.?

Yes, I too suggest omitting …transmitted through the trial of a ?telepathic phone?, after virus. Consider describing the virus, too, for dramatic effect.

…she must stop preparing for the world?s end and start saving it.? ??That’s vaguely interesting – if that makes sense; it sounds good/catchy, but does not say much. Narrow it down to specifics: how exactly or what must she do to start saving it?

Hope this was of some ?help to you.
