Vivere.

Nyx is a girl who can heal any wounds except her own.

When a king captures and murders her mother, she is imprisoned; forced to heal men of war who deem her lower than dirt and forced to marry the king she loathes the most.

Saval is a servant boy who just wants to mend his scars from the past, and to have money and food for tomorrow day.

They meet.

It goes downhill from there.
