Mature Women & Mothers in SFF

Mothers in SFF rarely live past the first few pages – dead mamas score big on the motivator scale. In truth, it's an easy trope to fall into, because what mother is willing to let their child go off to fight the big bad? But what about the moms who fight the big bad themselves? What about the ones who ARE the big bad? What about older women who have no offspring but are still the main characters of their own stories? Mothers and mature women everywhere, UNITE!
