Hold the presses! Crab Moon is about to go into another round of picture book reprints. But this new edition will include an update.

When I wrote the book, back in the 20th century, the accepted way to flip a horseshoe crab was by grabbing its tail. That's how Daniel does it in my story. Since then, we've learned that holding a horseshoe crab by the tail can injure the crab. The accepted practice, now, is to grab the horseshoe crab by the sides.

If I had written the book today, that's how Daniel would have done it. It's too late to change the story or Kate Kiesler's beautiful painting. But we are adding a warning to the facts about horseshoe crabs at the end of the book.

I'm glad Candlewick is being so diligent. And I sure hope no horseshoe crabs have gotten hurt as a result of my story. That's the last thing Daniel would want.
