Since November I've been at work on a book for somewhat older kids, 5-grade and up including middle and high school. The tentative title: ANIMAL MINDS: HOW ANIMALS THINK, USE TOOLS, PLAY, AND COMMUNICATE. This is such a broad, deep, fascinating subject, with new discoveries in the news almost every week. Some very smart humans are doing research, but--no surprise--they don't agree on what is known so far. I learned a lot, and keep doing so; no doubt that will be inserts and updates before this emerges as a finished book. That will take quite a while. Both an editor and an expert reader will no doubt find ways to change the text. Meanwhile I will be rounding up many photographs, which will be the main illustrations. I also look forward to my next research and writing project, which will be delightfully different because its intended readers are more in the first grade to third-or-fourth grade range.
