Reading suggestions
There are some texts that I consider to be fairly canonical because I've had to read them, or their authors, for various classes: Chopin's The Awakening; Austen's Pride & Prejudice; anything by Willa Cather, or by Virginia Woolf, if we want to revisit her. There's also The Handmaid's Tale, by Margaret Atwood. Un Lun Dun and the books in the His Dark Materials trilogy are all young adult fantasy novels written by men that feature female heroines; it might be interesting to look at portrayals of girls in male-authored texts. Un Lun Dun (by China Miéville) is very funny and would be a light-hearted way to end the semester. On the other hand, Caryl Churchill's Cloud 9 (a play) does some very interesting things with gender/sexuality/identity that might be a nice culminationto the course.
That's all I've come up with from scanning my library, but I'll post again if I think of others.
