Damn, I got here too late! I taught In the Time of the Butterflies this year, and really liked it as a teaching novel.
I also ordered THT to teach to my senior class but (a)we ran out of time/I got sick and (b) I re-read it for the first time in many years (I love Atwood, but I generally re-read Cat's Eye, The Robber Bride) and I was all fuck, the language in this is much more difficult than I remember. Granted, my students were mostly ELL/ESL.
It's funny that you mentioned Atwood though. One of the teaching positions I am applying for is a quite good all-girl's Catholic school, and I was just thinking how interesting it would be to teach Cat's Eye to a upper-level class.
Heh, I'm having a imaginary reading list for a Damn,ItCanSuckToBeATeenageGirl class in my head:
Cat's Eye
Girl, Interrupted
The Bell Jar
Buffy seasons 1 and 2, with selected highlights from 3-7
How the Garcia Girls Lost THeir Accents
short story "Boobs" by Suzy McKee Charnas
hmmm...this is before my morning cuppa....what else?!
