I can't imagine that you haven't already read Shannon Hale's post about books and gender and about how gendering book recommendations fails young readers—as readers and as people—but I want to share the link here JUST IN CASE you have somehow missed it. Because it's important:
I remember one middle school 2-3 years ago that I was going to visit while on tour. I heard in advance that they planned to pull the girls out of class for my assembly but not the boys. I’d dealt with that in the past and didn’t want to be a part of perpetuating the myth that women only have things of interest to say to girls while men’s voices are universally important. I told the publicist that this was something I wasn’t comfortable with and to please ask them to invite the boys as well as girls. I thought it was taken care of. When I got there, the administration told me with shrugs that they’d heard I didn’t want a segregated audience but that’s just how it was going to be. Should I have refused? Embarrassed the bookstore, let down the girls who had been looking forward to my visit? I did the presentation. But I felt sick to my stomach. Later I asked what other authors had visited. They’d had a male writer. For his assembly, both boys and girls had been invited.
