Margaret Atwood: Tales for all time

I've got Margaret Atwood's MaddAddam on my bookshelf, demanding to be read, but first I have to finish re-reading Cat's Eye, which is part of our AP English course. Life is tough when you're being forced to read Margaret Atwood!
My love for her books started with the first novel of hers I ever read - The Handmaid's Tale. When my students come looking for a great senior read, it's always the first novel I recommend. It appeals to them because of the dystopian theme - especially when they realize that it was written before the deluge of dystopian books; that it was written before they were born. So that's how I hook them. Then I leave it to Margaret Atwood to reel them in.
I read Cat's Eye in college, and then again in around 2001. I'm halfway through it now, and finding even more value in it than ever before. And I'm excited for my students - excited that this too could be a novel that resonates through their lives, as they finish school and move on.
And for me? I'll be moving on to MaddAddam. Life's good.
