1. Examples of kick-ass moms in genre fiction/media. Cordelia Naismith Vorkosigan, Sarah Conner, Nanny Ogg, Angela Petrilli and Niki Sanders on Heroes, Mrs. Murry from the Wrinkle in Time books, Grendel's mom, Vivianne in The Mists of Avalon, Weetzie Bat in Francesca Lia Block's books, Maureen in Heinlein's books, Lyta Hall in Sandman, Lwaxana Troi and Beverly Crusher in Star Trek: TNG, Molly Weasley, Alanna in Tamora Pierce's later books, Lady Jessica and Chani in Dune, Cersei Lannister and and Catelyn Stark in A Song of Ice and Fire, The Rowan and Damia from Anne McCaffrey's "Tower and Hive" series, Sue Storm, Jessica Jones, Linda Park West, Mrs. Frisby, Helen Parr/Elastigirl, Jane Roland and Catherine Harcourt in Novik's Temeraire novels, all of the elf moms in Elfquest.
2. Examples of rape and sexual assault in genre fiction/media - handled well and handled poorly. Mary Doria Russell's "The Sparrow" (well), everything Stephen Donaldson has ever written (poorly), Watchmen (done interestly almost-well in the comic, but overly graphic and resolution-free in the movie), Identity Crisis (well enough, I thought), Guy Gavriel Kay's Fionavar Tapestry (ugh), Buffy, Dollhouse.
3. Examples of "objects in stories and stories in objects". Obviously I'll be talking about my collaboration with Kyth, but besides that! I like the example of The Neverending Story.
Here's a thing about the moms. They must be moms in the course of the story. Aunt Mae was brought up, as she's a significant mother figure. But Peter's actual mother is killed offscreen before our story begins, as so many moms are. Jean Grey? She's technically the mother of Cable/X-Man and Rachel, but that's all alternate timeline hooha and she didn't actually raise them. We're talking about actual mothers who are actually raising kids and still living their lives.
