My favorite place to read as a child was under the covers with a flashlight. While the pleasure of being subversive and sticking it to The Man (who, in this case, happened to be a woman: my mom) no doubt played a role, more compelling was that I appreciated the sensory deprivation that facilitated disappearing into the world of a book.
My bedroom, with its white furniture and riot of stuffed animals, vanished from view, and I could submerge myself into the alternate reality of wherever I was traveling to—the Metropolitan Museum of Art with Claudia from From the Mixed-Up Files of Mrs. Basil E. Frankweiler, London with Sarah Crewe from A Little Princess or Paddington from A Bear Called Paddington, turn-of-the-century Manhattan with the five sisters from All-of-a-Kind Family.
This memory had slipped into my subconscious until I happened to mention to a friend, as a jokey aside, that what I most appreciate about my Nook GlowLight is how it facilitates reading in the dark. (And the “Plus” version is waterproof, should I wish to read in the bathtub by candlelight!)
