The Orkney Library in Scotland received quite a surprise when Harry Potter author JK Rowling showed up to their discussion of The Cuckoo’s Calling, which Rowling wrote under a pseudonym, Robert Galbraith.
In an endearing exchange on Twitter, the world-famous author hinted that she might attend the discussion, and the library told her they would keep a seat open and save her some lemon drizzle cake — Rowling’s favorite (like the twinkly-eyed Professor Dumbledore of her own invention, she is also partial to lemon-flavored sweets). Surprisingly, she did attend the book club discussion, much to the delight of Harry Potter and lemon cake fans everywhere.
The Twitter exchange contained a bit of playful banter and even a Potter joke thrown in for good measure:

And she actually showed up! Cake has magical powers.
