I know that my first L'Engle book was A Wrinkle in Time. I think it was that one that my Mom's friend Gail gave to me. I know that one of my first L'Engle books was a gift from her. A beloved author, and the solution to a vexing academic conundrum, all in one gift, given twenty-odd years ago.
Oh, and there is such a thing as a tesseract, my dears.
