Such an absolute tragedy, Muggles. Our hearts and prayers go out to all the families affected. I read they told children to shut their eyes as they walked out past those who had been shot
A Wrinkle In Time by Madeleine L'Engle
This was the first science fiction book I ever read and I still remember the impact it had on me all those years ago. A classic children's fantasy/sci-fi with similar underlying messages to CS Lewis's.
