This is a cover detail that eventually went unused, underneath the thermoreactive ink, to Keep Our Secrets, a 2012 picture book that had heat sensitive ink which was meant to disappear when you warmed it by rubbing your finger on it. In a hilarious turn of events, made even more amusing by the subtitle of the book "to be read in a whisper," the ink turned out to be not-so-sensitive to heat, necessitating the use of a blow drier to reveal the images under the ink. Sigh. Super funny way to read a going-to-bed picture book. Anyhow. Even if it didn't work how it was supposed to, it looked good.
