It’s “Summer Sisters: The College Years” in chapters 26-27 of Judy Blume’s seminal adult novel. Vix is finally at Harvard, hating her roomie Maia and struggling with all the BS analytical chit-chat that surrounds her. Caitlin is still in Your-Up, making all sorts of late night calls and having dalliances with a woman who cuts up panties (hello, Rusty’s diaphragm!). Alison and Jody talk about freshman year dorms and roommates, celebrity charity supergroup pop hits, Charleston accents, and gonorrhea of the mouth. Big felicitations to this week’s Blume Head of the Week Samantha WM!
