I just saw that
Zilpha Keatley Snyder has died, coincidentally two days after I was moved to reread
The Egypt Game. (I checked because it could have been the same day and it wasn't, but it was close.)
I also just learned that
Mary Rodgers died back in June and that she published a book called
Freaky Monday in 2009. I loved
Freaky Friday when I was a kid and the 1970s New York it describes was far more fantastic to me than the idea of body-switching.
