I basically stopped and cowered because of COVID-19 and my wife and I being high risk. However I’m now finally back writing again. I’m hoping to get the Arduino Nano Every book done by the end of June. Examples programs will be basically to show new features and how it differs from the older AVR based boards like the UNO. So the book won’t stand alone but is basically a supplement to Far Inside The Arduino and will be priced appropriately (namely, much less expensive).
