They say i was summoned

All the novels she usually read contained summoning to another world, but what if it happened during an inopportune time?
Liliana was met with the misfortune of just that: she was summoned while showering. Dragged away from her family on Earth, into an unknown world of swords and magic and expectations.
She was supposed to be the light to cleanse the world from miasma: the saint.
Fuelled by grudges and armed with the mindset of a rebellious woman from a modern society, she navigates the medieval times.

What is this new world like?
Is there a way to get back home?
Will she find a way to reunite with her family?

Nothing in the stories prepared her for this world, or what it would demand of her.
