Cool book with heat-reactive ink from McSweeneys’ imprint for children. It’s called, Keep Our Secrets. I learned about it through Very Short List: every page has one or more hidden surprises that are revealed by heat, like a warm little finger or a hairdryer. And, I, personally, don’t recommend the hairdryer. After all, it’s a kid’s book.
