In my opinion, your logline could use a bit of work. The logline would benefit if you included something about the mother's struggle to find an antidote to cure her daughter's condition--adding more conflict and tension. I'm assuming the mother has a change of heart and regrets her decision about the zombification and thus is trying to find a way to cure her daughter? At least that's the impression I get of where the story is headed based on the info available. Also, including a search for an antidote would add stakes that would pique the reader's interest even more. I hope this helps.

Thanks for the feedback, Sabrina! The mother actually doesn’t end up having a change of heart, but that just proves your point- that the logline could use a little more work. I’ll go back to the drawing board :)

We need to know what happens after the daughter becomes a zombie.

A different approach to the premise. It makes me curious.
