Keep Our Secrets by Jordan Crane ($15.95) is a book printed with heat-sensitive, disappearing ink. The publisher promises that the color-change effect does not wear out and is infinitely repeatable!
The story finds two young children touring their noisy house with fresh eyes, discovering along the way that all is not as it seems. Each drawing has hidden images beneath, visible only when the reader rubs the page to warm the disappearing black ink. Among the hidden images: a giant dog slumbering in a piano, a wishing puddle full of dimes, a raccoon that is actually a robot and a camera secretly made of cheese.
Coming in November 2011 from McSweeney’s McMullens, the brand new children’s imprint from McSweeney’s Books in San Francisco.
Ah that’s really cool. I wish my niece was old enough to play with a book like that.
