The Magician’s Nephew by C.S. Lewis (The Chronicles of Narnia #1) c.1955 (202 pgs)
What does this make, re-read number 28? At least. I devoured the Narnia books repeatedly as a kid and still love to pick them up again every once in a while. The adventures are always fun, and grounded enough that you could imagine yourself in them. The religious overtones (which I don’t remember noticing as a kid) are light and never overpower the story itself. This volume (although written after the rest) is where it all began- with an attic room, an evil uncle, and a pair of magical rings.
